Why Nancy Is Scrapping Its Magically Bonkers Monorail-Bus-Trams

[@TheTimTraveller]

A few things I'd like to add as footnotes to this vid: 1. The new trolleybuses arriving next year will be 100% electric - they will have batteries that can be charged while driving under wires, that can then be used for running without the wires for diversions, trips to the depot, etc. Until the trolleybuses arrive, there will be a temporary replacement service using conventional buses. 2. Fitting the TVRs with diesel engines just so they can go to the depot is a daft situation to get yourself into, but to be absolutely fair, it was probably the best solution in the circumstances: cheaper and quicker than installing wires, tracks, or building a new depot. It also meant the trams could take diversions if required. Still, the new trolleybuses + rechargeable batteries are a better solution long term. 3. As many of you have pointed out in the comments, there's an advantage of running on rails that I missed from my list: safety. If you are a pedestrian, or another road user, you always know exactly where a tram or TVR is going, and that it cannot deviate from the track. There are of course other pros and cons that I did not cover - it's only a 9 minute video after all - but this feels like the most important one.

[@stuarthedges3699]

I lived there 20 years ago when they were new and I'm sure I remember them running under diesel on part of the route. Maybe they just hadn't finished installing the overhead wires. If they failed to engage with the track at Callot they had to start the diesel engine and go around the block to line up and try again! Great fun and I'm really sad that I won't see them again but I do understand why they've been retired.

[@cedricklyon]

The new 24m trolleybusses will be built by HESS (Switzerland), with IMC (In Motion Charging) technology like the trolleybuses in Lyon or St-Etienne. The trolleybus will refuel its battery thanks to the overhead contact line during motion. The centrale part of the existing overhead contact line is to be removed, the rest wil be upraded. Fun fact : when a TVR was accidentally "dé-droppé" (without guidance) where it was supposed to be "droppé", the driver had to put an ⚠ sign behind the windshield to alert an incoming TVR driver that the clearence between them would be reduced. The track radius at the Gare station was 11m, but the vehicle was supposed to tolerate a minimum radius of 13m !

[@dank6514]

I wonder why they didn't just add a depot for these vehicles somewhere along the line, or at the beginning or end? That way they wouldn't have needed the additional diesel engine to drive across town. When decisions are made that make little sense, someone is likely profiting greatly at the expense of the citizens.

Ok ok, I was too sensitive, sorry.

[@Morall332]

I live in Caen, where there used to be exactly the same kind of tram. In fact, I arrived there pretty much a year and a half before this style of tram was fully discontinued. The sound the trams in the videos made when they accelerated and descelerated brought back memories... Fun fact: in Caen, the tram never got off the rail during normal service. In fact, the only point when it got off the rail was when it took the road to go back to its hangar (or whatever storage space they were using). No overhead cables on the road; it ran on a fuel engine (Diesel, I believe, though don't quote me on that). In fact, as part of the tram replacement process, they removed the cables before the tram was fully discontinued; so for a while, it ran on its usual track with passengers, but running on its backup engine...

@@mareksykora779 No, it's not the best solution for that. In Castellón de la Plana (Spain) they have a trolleybus with an optical guidance (markings on the road) and the bus follows this, so you don't need a rail to get close to platforms. es.wikipedia.org/wiki/TRAM_de_Castell%C3%B3n The TVR is nor quieter than a trolleybus. Due to the needed guide rail & wheels there is an additional unnecessary source of noise. When the TVR was introduced, there were several derailments. As a result, the contact pressure of the guidance wheels was increased, which further increased the noise of the guidance.

[@mareksykora779]

@@christian_maibaum It is quieter than a tram and much more accurate in navigating to the platform with less driver effort than a trolleybus. That's why it's the best. Optical guidance can be good, but the same can work with this navigation rail. It can also be used only as a source of navigation information for a much softer and completely silent navigation system. And much more reliable than just an optical system tracking some painted signs on the street.

[@robertheinrich2994]

I agree. it's so absurd, it could have been invented here in austria. it's basically translohr, but with the additional disadvantage that the middle rail does not provide a ground connection. so they have to use trolley bus wires.

[@maddydementhe]

Also, might be interesting to point out that Nancy didn't choose to remove the tram and put a trolley bus instead only because it was the "best" of the two options, but because they HAD to : the company that made the tram (bombardier) stopped making replacement parts for it... which is kind of a problem when your tram is 10 years old 😅

[@Clement-xy9iv]

I came all the way from Brest to see this thing last Sunday. I must say this was one of the most striking things I've seen. I've already done a few final rides of some legendary vehicles, such as the last Heuliez GX417 in France, but this TVR had a very different feeling. I actually had a tear in my eyes when leaving the train station and seeing these engineering beauties for the very first time of my life. First I can say that despite being an absolute technological disaster because of all the hundred of conception and construction issues these had, people were quite attached to this legendary transportation device. Actually I've seen quite some drivers literally crying at the end of their last service last Sunday. There was as well a lot of local transit enthousiasts as well as ones who came from all over France and even Germany and Russia to see te TVR one last time. I've had the chance to get a full carbide with a super nice driver as well, for an hour and a half he was telling me the story of the TVR and listing all the hundred and issues they've had with it for the past 23 years, and he wasn't even done when he left. At first this system was intended to last for 30 years at least, it ended up being fully retired after only 23 years. By the way, only a few years after trying to put it in service, Bombardier actually said this thing won't last more than 15 years, it only lasted longer thanks to Caen removing its system at the end of the year 2018 and sending all their TVRs to Nancy for free so they could keep it a little longer. As an engineering student, an absolute transit fan and a future transit engineer, this thing really inspired me and will forever be an emblem and a guide for my studies and my future job. It was such a great idea, that ended up being an endless disaster only because of some terrible conception. I'm going to write a full and very detailed article about this very special vehicle. I'm planning on going over the full history and political context of this device, as well as doing a deep technical analysis of the device, pointing out all the design flaws, possibly with technical documentation. This thing clearly changed my way of seeing engineering and public transportation. What a special vehicle!

[@insertdeadmeme]

Hello, I'm from Nancy and it's very weird to see the landscape I see every day in an video in English. Thank you for covering our weird tram ! If I'm not mistaken, there are at least 3 more reasons for the scrapping of the tram : 1) It's too small. It becomes very crammed during peak hours and it is sometimes impossible to get on (even though there is sometimes still space on the inside, people usually gather were there are pole to hang on to and so there is often a lot of unused space) 2) The trams are too old. If I'm not mistaken they have no spare parts anymore so they have to cannibalise their own trams to keep the other ones running. They have been breaking down a lot recently and the slope to get to Brabois is especially hard on them. One engine caught on fire, two trams were almost cut in half and so on. 3) It's very loud, especially when stopping. You can hear it from ~ 150 meters away. There is also another reason I'd like to mention but I'm not too sure about this one. The only source I've got is from someone who did a study on this as a project in a local engineering school. If I remember correctly the soil of Nancy is awful (it used to be a swampy area) leading to countless repairs of the rail.

Hey, I'm from Padua, one of the cities with rubber tired trams! If I have to be completely honest I don't really get why they exist, lol. We don't have a single hill in sight so a normal tram would work, the tracks get slippery when wet and they're pretty effective bicycle tire traps (and as a city with many cyclists that's an actual problem) so a normal bus would be better... And we already have buses! On the same routes sometimes! Not to mention that they're also annoying with cars, as they can't get around the stupid people and have to stop, while they ruin the roads by always passing on the exact same patch of asphalt that's regularly full of bumps and cracks. Edit: ah, I'm not the only one not getting it then. Good to know :D

[@tuttocrafting]

Yes, same in Venice. Here we have created a concrete patch with the rail embedded. This means that standard pavement machine cannot rework the street surface. Now streets are all bumpy. For what I've been told the manufacturer also stopped the production of the repair pieces so it's now very expensive fix those things. One big, really big annoyance is the noise they make. Why on earth are they that loud especially at 70km/h? They go up to 95dB... you need ear protection! Why they make crackling sound when they brake? One of the worse implementation of the tram I've ever seen. Rail switching not always works, so they re designed some stops. Trolleys would have been a better choice...

[@oleurgast730]

Not many people areware how fast technology has advanced over the years. Nowerdays computers make it possible to alow much more controll of movement of individual wagons. The "bus" has 3 segments. Quite long. With modern controls, just 50 cm extra track with is needed. But back in the days it would have been more than a meter, depending on the curve radius. You simply couldn´t drive such a long bus in the old city without tracks. So until the tracked tramlike bus started, only normal bussed were possible, reaching their capicity limit. Electronics were not be fit jet, to allow longer busses to be controlled trough low radius curves. Nowerdays long busses can be controlled savety through low radius curves. But around the millenium change, you needed "mechanical help" to keep a long bus on track. Inside the old town. Of course, on the peripherie without low radius curves, you never need a track. Or simply said: In the area with low radius curves you need something to keep a long bus on track. For the time the desission was made, this had to be done mechanicly. And now it can be done electronicly. A tram - or a "tram like bus" - has more capacity than a normal bus. Wich also means less drivers needed per passenger. At the moment. In 30 years people will look at our time and think about all the weird transportation systems. With self controlled cabs without any drivers, 2 or 4-seat mini "busses", maybe some bigger ones for groups/sightseeing. Why busses / trams at all? Simply the technology is not ready jet. But it might in 30 years. But even if it is ready earlyer, this does not matter - as you do not abandon a working system before you need replacement.

[@AlbertBenajam-ww1db]

There is ONE point in favor of the system. SUBWAY/ SURFACE In Boston MA, Philadelphia & Pittsburg PA and a few other locations USA (and other nations) there are street car/tram lines that run as subways downtown and then on streets with cars. These have trolly disadvantage on streets. But this would have bus movability above ground, and the in tunnels on track no need for steering, allowing for faster operations. The latter issue is why Seattle which once ran trolleybus in tunnel needing steerable TBs was converted to railed vehicles.

Brings back memories, I lived in Nancy (Vandoeuvre, to be exact) for 7 years and took the tram many, many times. Another thing you didn't bring up : there's a kink in the rail, just after the bridge that goes over the train station. You can see it around 6:20. Back when I lived there, the tram would often "derail" if the driver went too fast. They rebuilt that portion of the rail multiple times (I think I remember at least two) to make it shallower, but still the tram would have to slow to a crawl through that kink. PS : that incline after Callot is STEEP. Pictures and videos don't do it justice.

[@michelkuehn1745]

At the beginning, workers had to weld the rail in the chicane every night to repair it. This was due to the fact that the guide roller was not suspended (unlike the tires) and thus inflicted colossal pressure on the rail in corners.

Gosh, your video brings back memories! I was a student there for a while. I remember 2 noticeable events from back then: - Some time during the year, there is a free museum night and it's crowded because the city is filled (about 1/3 of the population) with cheap (ok, poor) students. Getting in and out of this infamous TVR takes a while longer. It caused delays so severe that we arrived before the tram to the city center, leaving from callot - on foot. We were going slightly slower than the tram itself. - There was a period with particularly virulent protests (by France standards) - they decided they'd block the tram path. So the drivers raised the guiding wheels in the middle of the course, turned on the diesel engine and started to run through the small one-way streets of the city center to go through. It was bumpy af, it sounded inside like the panels were about to fall off. Too bad you missed the TVR going to its parking, it's something to see it zooming along the freeway (it feels longer than a trolley bus and it's weirdly articulated when seen on the road amongst other vehicles). Thanks for your video though! TIL they retire it - hope it will be replaced by a trolley and that they'll put back the other lines too (they converted all to natural gas but it's currently pricy and risky to run - reliability and climate-wise)

The TVR belongs to a category of trains called "gadgetbahn". These are trains, also in an extended sense, that seem fancy, high-tech or innovative, but are not, as they bring more disadvantages than advantages. Another good example is monorails.

[@matsv201]

Everything is gadgetbahn before it's common. I would not call monorail a gasgetbahn, just because we in Europe dont understand it don't make it bad. Monorail got very good economy and quite high speed. It sort of have the speed of a Subway but the cost of a tram line.

[@MrJstorm4]

A lot of the appeal of monorails in the US was as an El for nimbys. Also if you're trying to make an El it is generally cheaper to build.

[@DJKLProductions]

@@matsv201 The modern monorail is a gadgetbahn because it is expensive to build, maintain and cumbersome. The switches are very susceptible to wear, cumbersome. These monorails always have to be built away from roads, as their thick rails and the space needed around the rail are not compatible with integration into the road network. Even saying that they are built for long distances instead of railway lines, i.e. not as a replacement for trams and metros, is almost hare-brained, because all systems of this kind are not standardised and are subject to patents. This means that if a city or region chooses a manufacturer, spare parts can only be purchased from that manufacturer, or the trains and rails can only be repaired by that manufacturer. After the construction of such a system, they can charge lunar prices for further services such as repair, as there is no longer any competition due to patents. In normal rail transport, there are many manufacturers of rails, wagons, locomotives and multiple units (trains without locomotives). There is a lot of competition and more compatibility, and there are standards. Standardisation also drives down costs, as there are standardised machines for standardised parts. In retrospect, the Wuppertal suspension railway and its prototypes were and still are gadget railways. The fact that this suspended monorail is still in operation and was restored at record speed after the Second World War is due to the unique situation in which Wuppertal finds itself. The subsoil here is too rocky for an underground railway, the city too narrow and elongated, as it is located in a valley, and a lot of traffic has to squeeze through this eye of a needle and thus through the city. Therefore, this was the only sensible solution. Wuppertal is the only place, where this type of train is not gadget. If this little summary of why monorails are gadgetbahnen that are completely overrated doesn't convince you, I can only recommend the many videos on KZbin that highlight the various aspects of such a system. All these videos come to the conclusion that normal trams and railways are still the best solution.

I think there are two more very positive points of the bustram. The rail. The rail makers the road as a tramlines and this makes it more obvious you cant park there because the tram can't move out the way and people are more hesitant to block the tram than a bus. The other. The rail. It shows for pedestrians and other drivers that there is big traffic to expect and the rail makes it obvious were to expect it. Still the negatives are huge.

[@RoyWiggins]

I guess they could leave the rails in and just have them there as a placebo

[@matsv201]

That is sort of one of the main motivation that is used for cities that want to install trams in stead of busses. Personally i think it's just a waste of money. A tram cost 5 times more than the same size bus. And it cost mot to maintain. There also exist 32m busses with self guidning rear axels that all follow the same line. And where it's needed there also is busses that follow a magnet line in the road that just automatically is turned on when you run over it and that is impossible to detail from. As well as inductive power supply.... but I have not seen it on a comersial bus, just prototype and trams. One system in Germany have it. There is a frensh city that have 3 rail trams that have the power in the middle, like a to train.

[@yrden99]

I live nearby Caen, Normandy (Northwestern part of France for those not familiar with our geography) and we had such trams for inner city and downtown commute for years. We replaced the original 2 lines by traditional trams, which are awesome, and added a new tram line to address massive traffic issues we face in the city nowadays (my daily 22km trip from my home in southern rural area to my workplace in northern inner suburbs takes up to 1hr during rush hours) The old tram was a nightmare. In the last year of exploitation, we faced 700+ failures, leading to MASSIVE problems and people not trusting our local and suburban transit system... Edit : As a side note, Caen respects road hierarchy and modern planning concepts, with some really nice neighbourhoods inspired by UK garden cities. Our main problem is arterial sizing and mass transit cluttering (too many bus lanes converge into downtown and lead to busline congestion) coupled with heterogeneous suburban transit options (some suburbs have too many options which doesn't always make sense, while some other suburbs are badly connected and not really walkable and require car usage for nearly anything)

6:54 this is pretty common on many trolleybus systems. The Arnhem trolley buses - at least the Daf ones running from the 60s till the 90s - were delivered with a small engine that allowed a top speed of 50km/h. Either for use when the power line goes down and you gotta move it out of the way, but also for returning to depot.

I forgot whether they went through with it, but Arnhem was going to get trolley buses with decent batteries to enable flexibility on the far ends of the route, only needing electrification at the center section. Which then also makes a diesel engine unnecessary.

[@QemeH]

There is another advantage of a rail-guided system that isn't immediately obvious: predictability. This is basically what makes trams easy to integrate into pedestrian zones while buses are a nightmare to mix with other uses. The speed, acceleration and direction of a tram can be easily calculated even by people who have never been on a tram - and there are definitive "safe zones" where the tram positively CAN'T ever be. This is not the case with buses. For city planners it is actually the second most important reason to built a tram over BRT (after capacity).

[@matsv201]

There are other guided.busses that use magnets (under the road) and they typically either have tarmack in a other color or concrete bricks for the wheels to not have the problem with the wheels destroying the surface.

Hi Tim from Spain. I liked trolley buses, they were quiet, efficient and smooth.

Smoothness really depends on the driver. 😄 Electric motors are famously torque-y, so if a driver really puts his foot down, the acceleration is much more intense than with a regular (diesel) bus. Can be a bit of an issue if some people are still walking to their seats.

Yay ! I m from Nancy ! I didnt knew all those things, but you can add to the advantages that there is many "dissengage stations" if the tram needs to make detour for any reasons (constructions/repairs on his tracks, roads block by one of our famous french strikes,a ccidents...). The Nancy tram was considered as one of the slowest in France, and the most noisy one. A "fun" thing is that only few days after it stopped the tracks became orange of oxydation by lack of friction, making the tracks looks a decade old in less than a week ! Great video, so glad you came here :)

[@TramChris]

Great Video! Another interesting story about the TVR: Just a few weeks after the grand opening of line 1, it had to be closed for almost a year to improve the operational safety. As it turned out, the trams had a high risk of derailing, which resulted in some damaged trams and trolley poles as well as injured passengers. After that, strict speed limits were introduced - especially in tight curves, where the TVR should have been faster than a regular bus. I've been in Nancy two weeks ago. Though being quite interesting to watch, the TVR was very slow and uncomfortable.

[@charleslambert3368]

you'd think that if it derailed it could just start being a bus again. but then again a tram that sometimes becomes a bus with no warning sometimes is not much easier to drive than an actual bus.

[@le_traminot_nanceien]

There was only one accident that resulted in injury, the majority of the others were electrical insulation faults and sensors that switched on unexpectedly. The problems took a year to fix. It was not a question of derailments but of problems with the rear axle which became uncontrollable! The incidents had occurred in unguided areas.

[@FelisSilvestrisBE]

Oh, I like this content. Now, as a Belgian, I am sworn to defend this system ( I previously didn't know about ) and say I can think of a few more reasons to have one: - Electric bus/tram, thingy circa 2002! Well, you have trolleybusses, but they lack capacity ( so far I can remember the ones from Ghent, back in the day. They're gone now ) - New trams have a WAY bigger capacity than a new bus, and this seems to combine the two. I'm not sure you can find many skillful chaufeurs to drive a 3 sectioned bus in the streets of Nancy. AND! No, that's it. I'm out. Also, they could've electrified the route to the depot and/ or have a maintenance vehicle tow the tram/bus/thingy. Every city with such a tramline has such a towing vehicle. I love your content, thank you ^^

This Translohr system is quite famous in the Veneto region of Italy, which has two similar systems, one being in Padua and the other one has two routes between Mestre and Venice. So sad that this type of transportation will be gone shortly. Seemed so nice. It might be cheaper than a conventional tramway, but more expensive in terms of maintenance, which is continuos

[@urbanfile3861]

To go on a steep hill a tram could use a rack rail. There is a tram line in Italy, Trieste-Opicina, in the city of Trieste, that to go up hill uses a rack rail. It's very peculiar because the tram cab (an old fasfioned model from the '30s) can't get on by its own and it's couppled by a tiny 'tractor'. To remain in France there is Lyon's metro line C. A former rack rail tram now 'upgraded' to a metro line.

I think that the Belgian bus company Van Hool also makes a double bendy bus, where the tyres of the rear parts of the bus exactly follow the tyre tracks of the first part of the bus. I believe they are used in the Dutch town Utrecht.

[@ft4709]

There’s several companies that do this with Busses beyond a certain length. However, this means the rear axle has to be steered which makes the vehicle more complicated and harder to maintain. I believe with the TVR the steering part was done by the guide rail alone and thus simplified it a lot. Plus the turn radius apparently is still significantly smaller with a guide rail, leading to an easier integration into the city. Same with crawling onto platforms for step-free access. I’m not against trolley busses or double-articulated busses but I do think Nancy should have gone the Caen route and replace this system with a conventional tram.

I travelled everyday in this tram for 4 yrs, and as a Mechanical engineer I was surprised to see the versatility and genius strategy of this system, because it is 1) using guide rail to steer in fully autonomous driving mode. 2) using massive wheels to handle the load on otherwise normal road 3) they can add suburbs to the existing routes without infrastructure expenses driving it as a long bus 4) when there are no electric cables, just start the Diesel Engine and keep going.

[@alfrredd]

The road damage, unnecessary track and having to carry a diesel engine all the time doesn't seem too genius to me 😅

[@Mqtisse]

Theres another advantage, which is maybe often overlooked, and that is that having a rail makes it more "permanent". It more visual, people see it and know theres a tram/bus and therefor will look to use it. Being more permanent also makes it so that it cant simply be cancelled or removed, like busses and trolleybusses. More physical infrastructure comes at a higher cost (generally) so you cant justify ripping it out as easily, making the system more resilient against policy changes.

@@incalescent9378 There are a lot of downsides to batteries (that aren't much talked about because they detract from the cool new tech). Overhead wires are fundamentally superiour technology wherever they aren't non-viable. Basically, any battery with high enough energy density to be usable instead of an internal combustion engine or overhead wires is also an absolute nightmare safety wise. (ever seen what happens when an electric car decides that being on fire would be a great idea? Goes up in seconds, burns for hours, can't be put out short of burrying the car in sand, so it just gets cordened off until it burns out... now consider that a bus needs more, bigger, batteries of the same type.) Now, for the situations where it would be useful for a trolley bus that usually runs on overhead wires to be able to briefly opperate independently from those wires, much lesser batteries (made with much less dangerous materials) or well designed capacitor banks will do the job well enough with no real problems. Enough to avoid the complex nonsense that is overhead wires at the depot or major intersections between multiple tracks (though you should really still run wires Too the depot, even if shunting and switching within the depot doesn't lend itself well to them). Also? The wires aren't ugly. When you're actually There going about your life and not actively looking for something to complain about, they blend in, often to the point of functional invisibility, with no problem. Well, I suppose if your living room window is exactly the right height in a multistory building it might be of some limited concern (though, trade off, birds like hanging out on wires, so if you like birds, it's possibly a win.) Now, the pole etc. that hold the wires up Can be ugly.... or they can be really nice and significatnly add to the character of the street, exactly the same as the poles holding various street lights and the like (heck, they can be the same poles!)

I experienced that multiple times. It worked but was awfully slow :) - The tram was famously unreliable. One of the reason for this unreliability was the mono-rail itself deterriorating much faster than anticipated. - The mono rail system was awfully noisy, proably due to the previous reason. It was currently ironically quiter without the rail on road. - I heard that the Nancy tram TVR "concept" itself was co-designed as a prototype by one of Nancy engineering school. I always considered it was a pretty bold move to make a prototype straight into the backbone of the city transport itself. This is not so surprising it turned out into some reliability issue.

They’re a good match for the French Metro trains that have rubber tyres, which I dearly hope TFL would adopt so I can avoid hearing damage from riding the Tube, particularly the Central line and even more specifically, Bank. I still remember being mind blown when I first saw the French trains and the joy of their quietness.

[@lzh4950]

The rubbing of rubber tyres against the guideway makes a lot of noise in tunnels too though I remembered, & as rubber isn't as rigid as steel, rubber-tyred trains will face more body roll than steel-wheeled ones

[@LMB222]

Those rubber tyred vehicles have much higher rolling friction and are really only useful in hilly places.

[@lukestevens8735]

Sad to have missed it but certainly an interesting idea. Sometimes you just need to try things to know they don't work :)

[@julienjoly399]

Actually I'm from Nancy and I heard that they wanted to build a cable car before choosing to put these trams. You also forgot to mention that this line is really fast compared to other buses ;)

[@le_traminot_nanceien]

The cable car idea has already been abandoned!

[@raisinbrandrew1947]

This is the funniest thing I’ve ever seen. I absolutely love it.

[@williamgeorgefraser]

I live near Nancy and am a regular visitor. I had no idea this was about to happen. Thank you for the video.

This reminds me of my local city of Arnhem, which has normal Trolleys (one of the largest network in Europe), with some fun history involving a problem with hills (yes in the Netherlands), Germans blowing up the old tram infrastructure. And in the near future they're going to run quite far out (all the way to Wageningen) on Batteries which will charge of the wire while in the city centre. The old trolleys had diesel engines, and was always weird seing them drive by with all the noise and smells of a small not efficient diesel engine

[@rjfaber1991]

Ah yes, the hills. As a fellow Arnhem resident, I'd dearly like to invite anyone saying that the Netherlands is all flat to come to Arnhem and walk up Monnikensteeg. That should change their mind.

[@SamAronow]

My gadgetbahn senses are tingling. If Nancy thought a tram couldn't handle an incline in wet weather, they should have asked San Francisco for a second opinion (ETA I'm talking about the electric trams, not the cable cars). EDIT: I'm also not sold on the cost angle, since that only applies to upfront construction costs, whereas trams can handle significantly more traffic relative to maintenance costs in comparison to buses, in addition to a much smoother ride.

[@Nhkg17]

Or they could keep much cheaper trolley buses if they don't have enough riders to justify a tram. Gadgetbahn is almost always a bad idea...

[@aburrki6732]

well to be fair, san francisco's cable cars are... pulled by cables, they're specifically designed to handle inclines

[@TheRandCrews]

San Francisco’s trams don’t have tracks they’re cable cars, literally cable pulling the cars underneath the street. Unless you’re talking about the Muni Metro they don’t have that steep of inclines and more so gradual.

[@ianroberts6531]

Or Sheffield - we have conventional trams with a 10% gradiant, and the vehicles were specified such that one tram could push another one up that gradiant if required to rescue a failed vehicle.

[@SamAronow]

@@aburrki6732 I'm not talking about the cable cars, I'm talking about the electric trams, and specifically the section of J Church that goes through Dolores Park. And back when E Union and B Geary existed, they managed hills decently as well. Not as steep as Nob Hill like the cable cars navigate, but decently. Not to mention the hills formerly navigated by the Los Angeles trams (Yellow Cars).

[@davidcummings2020]

It's so forward thinking and allows cities to extend and experiment with different routes .they are also fully electric and clean. Poor planning on behalf of the city especially on the depot location.

[@lisette2060]

Poor planing? Notice Nancy as well as other Towns with houses and all, existed way before these bureaucratic monsters were invented...

[@donnyrossi]

In the netherlands we have them also, they are called trolley busses and dont have to use the track. They drive in Arnhem

[@Nicowild]

Thanks to you, i now understand what was all of this Tram stuffs in a City i've been in for 3 years and known for more than 15.

[@captainufo4587]

Wait. The tracks are used only to guide the bus. It's the tires which do the driving, right? Then why do the track stop at any point? You can still go uphill and keep it guided by the central track.

[@eljanrimsa5843]

Good question.

[@allanlindskoog]

I think they accidentally admitted that they really didn't need the track. It was cheaper not to build it there (as it would have been cheaper to not build it anywhere.)
