Whoever thought of painting Tube and then Underground trains to match their respective logos with the doors picked out in red or orange was really brilliant. A continuation of their history of graphics and architecture innovation that is not seen elsewhere in transit.

[@DavidShepheard]

Jago needs to make a video about that, but when the D-Stock trains first came into service, they decided to keep them in naked aluminium (so they had a silver look to them). We had a few idiots, who liked to tag trains, and then London Underground would have to blast the paint off, to try to get them back to the aluminium look. And the trains just ended up looking dirty. At, around the same time, there were some disabled campaigners, who were protesting about the way that almost all public transport blocked them from using it. Two big changes that TfL had to make where: • Replacing Routemasters, with buses where wheelchair users could get on and • Underground trains needing to have doors and bodies that were of contrasting colours. London Underground uses red, white and blue in it's roundels and they picked those same colours, as the colours to put on the trains. Other railway companies did also get ordered to change their door colours. But they sometimes look more like they are following the law, while TfL makes it look like it's part of the style. And it looks so awesome, it makes you think it's always been that way. (And, if the TfL trains did get tagged, they could make them look clean and new again, instead of needing to scrape the aluminium bodies.) If Jago ever does a video, where you see each London underground train stock before and after it got the red, white and blue makeover, you will be surprised how old some of the trains look, in their original colours.

[@AndreiTupolev]

The current livery was adopted in the 1990s when the trains were refurbished. It's certainly an effective livery, more striking than the brand all-red Bus livery

[@synchromystici5m]

There were several other colour configurations trialled (videos can be seen on KZbin), but I believe the winning design wasn't trialled, and was actually suggested by a London Underground employee who wasn't on the design team. It's by far the most logical, as it's similar to the roundel - a blue horizontal line across a white background, with red coming in vertically.

In Berlin/ Germany, the equivalent to London's overground and the underground trains cannot share the same track, not only because different standards, but because before the law, the "overground" is a railway and the underground a tramway. Also in Berlin, where underground and tram are different networks

[@MarioFanGamer659]

Though it should be noted that the S-Bahn (the aforementioned Overground equivalent) also is fairly similar to the LU, being considered a second metro network alongside the U-Bahn, and thanks to the use of 3rd rail mostly has got exclusive tracks (Germany uses overhead wires elsewhere except Hamburg) except at the stations Karow, a stop of the RB27 (which uses diesel trains), and Birkenwerder, a stop of the electrified RB20 which uses EMUs and as a side effect, the tracks there both have 3rd rail and overhead wires.

[@zaphod4245]

I remember being on a train out of waterloo going to Southampton and being very confused when we went to the right at Clapham Junction, onto the Putney branch, only to then use the curve to get back onto the main line at Wimbledon, apparently there were some engneering works on the 'fast' tracks between Earlsfield and Wimbledon, hence the diversion.

[@ajbonmg]

I went on a Deltic-hauled railtour in 1981 ('The Wessex Deltic') which was routed on that line too. It was interesting to see the surprised faces of the commuters waiting at Southfields and Wimbledon Park for their District Line train when a Deltic roared through. 😀

The very last stopping train of the night to Strawberry Hill via Wimbledon uses the line from East Putney to Wimbledon

[@bugsby4663]

I used to work at Wimbledon Park and whilst the mainline trains didn't stop to pick up customers, they did stop due to the signalling, which then was still mainline signalling. They still sometimes used slam door trains, which meant that unless I was told beforehand, I couldn't do a PA unless I happened to see one on my monitors. This was mostly happen late at night and the unfortunate customer would end up in the Wimbledon depot.

[@metropod]

Prior to the legal distinction between a rapid transit service and a mainline railroad in the US, we used to have such mixes quite often. In fact, the narrow loading gauge of New York’s Interborough Rapid Transit and the wider track gauge in Philadelphia on the Market Frankfort Line were created specifically to discourage such connections onto their tracks. Ironically for its first few years the IRT had a track connection to the Long Island Railroad at Atlantic Ave in Brooklyn. On the flip side, New York’s other private subway operator, the Brooklyn Rapid Transit at the time, built up its operations by making such connections. Until WWI and the creation of the United States Railroad Administration to temporarily nationalize the rail network, BRT trains ran on LIRR tracks to the Rockaway and LIRR trains used BRT tracks to Lower Manhattan. When the Federal government created the USRA, they didn’t want to get into the local transit business and so declared the mainline trains were legally a distinct concept from rapid trainer trains. Though this basically was a pile of BS since the subway continued to share tracks… WITH FREIGHT TRAINS. Thing is, the BRT built its system by buying up what had otherwise been “mainline” railroads in southern Brooklyn. One of them, the South Brooklyn Railways, legally still exists as a mainline railroad company, despite being a wholly owned subsidiary of the Transit authority. The line ran from the waterfront in the Sunset Park neighborhood to the main subway repair shop complex, the Coney Island Yard. And to reach it, for a few blocks, it runs on the tracks of what is now the D train, between 36th street and 9th Avenue stations. It then exited the subway and ran on the streets to Coney Island. The section west of the linkup to the subway is still in use, as it’s one of the ways we (I’m a transit employee, train conductor) get deliveries of new equipment, as the tracks actually do connect to the mainline rail network.

[@raakone]

My understanding is that it's "leftovers" from something like that why the PATH is considered a "railroad", under federal jurisdiction, rather than being a subway. Back in the Manhattan Transfer days it did quite a bit of sharing of trackage with PRR, and there were even PATH/PRR jointly owned rolling stock at one time. To leave federal jurisdiction, shortly after SEPTA got the Norristown High Speed line, they severed its connections.

[@JuneNafziger]

@@raakone I believe PATH is also like that because it basically was a mainline railroad until the Port Authority bought it and it's terminus and built the World Trade Center on top of it

[@metropod]

@@JuneNafziger effectivley, yes. the upside is it allows PATH to use mainline rights of way. I've stood on the platform at Journal Square PATH station as a Conrail Shared Assets train passed on an unprotected side track. Literally the only thing telling you it wasn't a PATH track is no 3rd rail. The planned extension to Newark Airport station is actually helped along by this status.

The track between Harrow on the Hill and Amersham is the only example which is owned and managed by London Underground rather than Network Rail.

Aah, Wimbledon LUR with with the track layout with the infamous conrail gap, with "The Box" containing a heavy jumper cable 1" (to manually clamp between conrail then car shoes) to get a train back in service and passengers off-loaded (LUR - no rescue/standby Diesels).

[@sjoerd5629]

The Rotterdam metro also shares tracks; Between Schiedam and Vlaardingen Oost (lines A and B), the track is shared with occasional cargo trains (the line uses a former mainline railway, and some cargo trains still need to use it). And between the stations Leidschenveen and The Hague Laan van NOI on line E, the track is shared with trams from The Hague tramlines 3 and 4 (all stations being equiped with platforms at two heights; high for metro's, low for trams).

[@johnjephcote7636]

I last worked at the older Watford Jct. in 1967 but we still called the dc the 'New Line'; but at that date it was only half a century old.

[@stefanhaustein]

Interesting bit about power in shared sections: In contrast to the underground, "regular" trains only use a single "third" rail on the side -- no fourth rail in the center -- for power (and the running tracks for ground). So how does this work on the same track? According to TfL: "As of 2019, In areas where London Underground and third rail rolling stock share tracks, the centre conductor rail is electrically connected to the running rails. This still results in a 750 V voltage but in a 0 V/+750 V configuration." "The original configuration is nominally 630 V (voltage), with a −210 V centre conductor rail and a +420 V outside conductor rail. This is the default configuration wherever deep-level tube trains operate. Beginning in 2016, sections of the sub-surface network were reconfigured to a 750 V configuration (−250 V and +500 V rails)."

[@althejazzman]

I was wondering about the electrical compatibility too. So does this result in a compromise where one type of train sees less voltage than it would on it's own dedicated track?

[@wasmic5z]

@@althejazzman In the Underground, the usual voltage is 630 volt (+420 on the outside and -210 in the centre). In the shared sections, it used to be +630 on the outside and 0 in the centre, because the middle conductor rail is bonded to the running rails. This means that both Underground and mainline trains would be running on Underground voltage. But a few years ago it was changed, so now the shared sections have +750 V on the outer rail and 0 V on the center rail. And apparently they're also upgrading parts of the exclusively Underground lines to have 750 volt operations too, but as +500/-250 instead. Regardless, 630 volt is within the tolerances of the mainline trains, and 750 volt is within the tolerances of the Underground trains.

[@iankemp1131]

That's very interesting. I had always thought that the centre rail was an earth rail only, but TfL indicate here that it can carry a substantial negative voltage. So stepping on the centre rail, as well as the outside rail, could do you a lot of damage (although both have a lower voltage compared to earth than the 750V d.c. on third rail).

[@althejazzman]

@@wasmic5z Thank you for the explanation.

[@netking66]

@@wasmic5z There is an even more extreme example at Italy's Ventimiglia station just over the border from France. French locomotives running into the station are dual voltage 25kV AC / 1500V DC, while Italian locomotives are 3000V DC. A French locomotive entering the station changes from AC to 1500V DC. A 3000V DC Italian locomotive has to tolerate 1500V DC when entering the station.

I saw a documentary some years ago on Metroland (at least 20). They wandered out to the field where Verney Junction was. Its was just about possible to see traces of the Metropolitan line joining what was the "Varsity Line" (Oxford to Cambridge) and the former link off to Buckingham to the north. What could have been, eh? However, these days Verney junction might see its railway (if not the station) re-opened in a year or two as the new East-West route reconnects Oxford and Cambridge. Whoda thought? Not Dr Beeching, certainly.

[@MercenaryPen]

actually the Varsity Line was one of the routes that Beeching wanted to keep open to serve freight services between East Anglia and South Wales. My understanding was that the BR Board itself recommended the varsity line for closure

[@gnhansen29]

The sharing of tracks with mainline trains is one of the things that fascinates me about the London Underground.

[@MarioFanGamer659]

It's still impresses me how the London Underground was mostly developed out of (competing) mainlines and not out of trams to the point where the Underground (particularly the Metropolitan Line) has been more compared to the S-Bahn of Berlin than its U-Bahn. Conversely, it shouldn't be too surprising to find mainline railways at some places due to this history. This video also made me realise that Frankfurt has plans to extend its U-Bahn, with inspiration of Karlsruhe due to the different voltages of both systems, to run with the mainline, even replacing some lines (most notably, the Sodener Bahn, a former S-Bahn line and current RB11). The S-Bahn, which is developed out of normal railways, also shares track with the mainline, though that one isn't too special because many other post-WWII system do this as well (dedicated tracks are expensive, for that matter) and is mostly more of a disadvantage than a curiousity (no level boarding, congestion). There still is a case where a train drives on dedicated S-Bahn tracks and that's within Darmstadt, between Arheiling and the main station, where the route of the RB82 crosses the S-Bahn tracks and runs on them for around 100 metres.

[@RogersRamblings]

On the subject of station ownership and traffic, Ealing Broadway became a BR owned and operated station although most of the passengers were LT's. The Central line to Ealing was built by the Great Western and the Central London Rly had running powers. It was one of the few places where three aspect semaphore signals were used. The GW then laid two more tracks from North Acton junction to serve the milk depot off Wood Lane.

[@kgbgb3663]

Are the lines alongside the Central Line that used to go through East Acton, but are now lifted? I hadn't heard about the milk depot before. (Do you know where it was exactly? I can't see it on railmaponline.) I thought that those lines were built by the GWR mainly to give it a better access to the West London Line (and so to the southeast of England) than North Pole Junction, which was always unsatisfactory. (I think I read that in the really early days it had a level crossing between the two railways rather than a bridge!) If I recall correctly, it was part of the GWR's early twentieth century attempt to shake off the nick-name "The Great Way Round", which also involved building the direct line to Birmingham, partially shared with the Great Central. That line connected with this one at North Acton, according to CartoMetro. I can't remember where I read or viewed the information, but I believe the route was originally twin tracks shared by both companies, then it was quadrupled so each could have two tracks, and later the GWR's tracks were lifted. Presumably that was after nationalisation, when it was decided that GWR could reach the WLL by looping up the North and South Western Junction railway to the LNW lines at Willesden Junction, and then picking up the WLL at its beginning. I watched a cab video of a heavy aggregates train doing just that on its way from Acton to Purley a while back, on the "DadRail" channel.

[@RogersRamblings]

@@kgbgb3663 Doubtless the North Acton to Wood Lane section was laid to serve a variety of purposes. The later pair were on the north side of the present Central Line roads. The GWR's "New Road" from Old Oak to Aynho was joint with the Great Central between Northolt Junction and Ashendon Junction. The GC wanted an alternative to the congested Met /GC joint north of Harrow on the Hill. I'll try and find the milk depot location.

I'm old enough to remember when the stations [sic] at Ealing Broadway had separate entrances. The mainline entrance was where the station now is, but to the left as you go in and some way along the street (maybe six or a dozen shops) was the Underground entrance with the distinctive blue canopy. The stations looked totally separate from the road. They were also run separately, but there was a lockable gate connecting the LT platforms from the BR platforms. When the Tank engine hauled "Push and pull" service was arriving/departing from/to Greenford the gate was opened and a ticket collector checked you had tickets entitling you to be both sides of the internal barrier as you passed through. I was aged about 6 at the time and not yet enough of a geek to notice whether the guy was in BR or LT uniform. (And yes I'm sure it was a guy: I was a bit older before I saw a female railway worker anywhere outside of the buffet facilities) I guess the stations merged so that they could sell off the frontage for another two or three shops.

I've enjoyed these Tube videos. They've left me with some thoughts: 1. Between 1965 and 1967 as a small boy aged 7-9 I commuted from Wimbledon to Gloucester Rd where I went to school. An incredible thought now. My Saturday entertainment was to get a 'blue rover' ticket which allowed me to ride all over the network all day on a Saturday. Again, extraordinary that I was allowed to do this. Otherwise I would use my season ticket to go to South Ken at the weekends to visit the museums. - as it happens, I live in Lincolnshire now but the other day I visited my very elderly father in Wimbledon and took the Tube out there. All very reminiscent except the trains are completely different now. Some of the stations have scarcely changed. 2. I remember that the Tube carriages alternated between smoking and non-smoking: carriages 1 and 3 were non-smoking, for example. Rushing to catch a train might inadvertently involve getting into an even-numbered carriage which meant being asphyxiated and seeing the floor covered with ash and stamped-out dogends; it was utterly revolting. 3. A very particular memory was the rolling stock. Occasionally, if you were very lucky the train that rolled in would be one of the very old ones. They were distinguished by having a higher central roof section like a basilica and inside there was a lot of varnished wood and rather plusher seats. I have no idea how old they were but they belonged to another era and were much more stylish. 4. I sometimes had to change at Earls Court. I remember watching rats scuttling about among the cables along the wall opposite the platform. 5. As a child back then I was delighted when an early Doctor Who series featured the Yeti living in the Underground tunnels. I don't remember which station(s) was/were included.

[@mallardtheduck1]

The line you refer to as the "GW Birmingham line" was actually called the Great Western & Great Central Joint Line. Given that fact, it's not surprising that both railway companies ran services over it... Nowadays, passenger services over it run from the GCR's terminus at Marylebone, the original connection to Paddington has been lost (although it's still theoretically possible to access the route from Paddington via the Greenford branch).

[@iankemp1131]

The GW&GC Joint was a nice collaborative venture. The GW wanted a shorter route to Birmingham, the GC wanted an alternative to the busy Metropolitan section, and they covered much the same tract of country. Rather than compete to try to get there first, they shared the costs, and the joint line even included the existing GW track from High Wycombe to Princes Risborough. The existence of the GW&GC joint line also made the Metropolitan less uncooperative with the GC about sharing train paths on their own line, as the GC now had an alternative.

Leyton to Ongar and Newbury Park to Woodford via Hainault, which is part of LT Central Line, was in fact owned by BR till 1971, and there was a mainline connection from Stratford to Leyton. and Newbury Park to Seven Kings and Ilford. Of course, Finsbury Park to Moorgate, which is a mainline railway, was originally part of the LT Northern Line until the Moorgate Tube Disaster. Whilst Waterloo to Bank, was original part of the Southern Railway (LSWR) prior to becoming a LT line with the advent of the 1992 tube stock. The East London Line with a connection from Shoreditch to Liverpool Street, was LT, now Overground. Also the Jubilee Line Extension, runs over the part of the trackbed of the mainline that went to North Woolwich. While the Docklands Light Railway deserves a whole mega chapter !

[@sams3015]

No one needs to know this but when I was a child I thought the London Underground was connected to the Paris Metro by the Channel tunnel. That would be the ultimate shared track scenario but I wonder if something like would ever happen in the UK say like a giant Liverpool - Manchester system?

I used to live by Wimbledon Park a few years back and I remember being so confused seeing a non underground train head south!

Before the Wimbledon to East Putney line was owned by London Underground (the station signs were standard BR signs and the staff wore BR uniforms) there were no issues with maintenance. Nor were there after LU became the owners - until 6 November 2017. Just north of Wimbledon Station there is a section of track connecting what is still Network Rail to the line now owned by LU, and used by the occasional trains mentioned in the video to reach Waterloo via East Putney. On that day, a train derailed on the link line when the rails came loose from their sleepers and separated, and the train dropped into the four-foot. The subsequent investigation revealed that LU thought that a 120 metre section of the link was owned and maintained by Network Rail, while Network Rail thought it was owned and maintained by LU, so that it was inspected and maintained by neither for some 23 years.

[@ZGryphon]

I had to go back and take another look at that sign off to the side at 2;37. I can't help but think "toilet for the disabled" would have been a better wording. As it is, it just makes one think, "Surely it would have been cheaper and more useful to just fix the toilet rather than put up that sign." :)

It's the poignancy of contrasting the histories of so many lost lines with my local radio traffic news describing so many hold ups on the roads into London that has me shaking my head in disbelief at what a mess we make of transport. Many years ago a lady who was recently arrived from an African country told me that "For such a small country you people spend a lot of time just travelling around in it. Why?"

[@AndreiTupolev]

London had very very few line closures compared with much of the country. It was virtually unaffected by Beeching. The only lines that have really been closed are duplicating routes, usually built just to compete with another company, and obscure branches and spurs

[@Ogrecrusher]

The timing of this video is spooky, I was literally googling pictures of Mainline trains at East Putney earlier today to show my colleague.

[@bobmcnob23]

One side effect of this means that when there are Network Rail strikes (i.e. not Underground strikes) then service on the Wimbledon-East Putney branch of the District line is hugely reduced/delayed while the rest of the Tube network is unaffected. I commute from East Putney to Wimbledon, so I’m now keenly aware of the fact that this bit of line is shared!

[@Psevdonim123]

Also timetables are a mess. Because LUL trains running on NR are technically National Rail services they have to have an NR timetables, which isn't really surprising by itself but those things are weird, because they don't show LU stations in them (they have a placeholders for some LUL stations so DMI's can show underground trains "correctly") For example District line train to Upmister from Richmond is shown on a timetable as a London Underground service to Upmister Underground calling at Kew Gardens, Gunnersbury and Upmister Underground (to which apparently the train teleports itself, because none of the intermediate stations are shown, even Barking which is managed by c2c). Bakerloo has the same issue but it's even weirder because sometimes DMI's on stations north of Queen's Park show something like "LRDDEAC" without any description, it stands for London Rd Depot which basically means that train terminates at Waterloo, but how a non train enthusiast is supposed to know? BTW, despite that section from East Putney to Wimbledon is shared it's still operated by LUL (same with Met to Amersham and Chsham), which means that it probably won't be affected by NR strikes, however Richmond branch on District and section between Queen's Park and Harrow and Wealdstone on Bakerloo are operated by NR, which means that they'll probably will be affected by NR strikes

[@thesteelrodent1796]

the Danish railroad was built on the cheap, almost entirely between 1846 and 1888, so there's a grand total of four tracks through the central city in Copenhagen. Two are for the S-trains - commuter trains - and the other two are for all other trains, and then north and south of the central part the tracks split up into their individual lines. Because of this it's not uncommon to see freight trains on the commuter lines, especially on the circle line, F, since it's the original line around Copenhagen from 1846 and it's the only way for freight trains get across the city without going through the very busy stations in the central city. This circle line connects the abandoned freight yard at Svanemøllen north of Copenhagen with the freight yard at South Harbour (which no longer functions as a harbour) and up until a few years ago half that line was strictly for freight. Another issues with this is that our commuter trains run on 1650 V DC while the main line is 25 kV AC, but both use overhead wires, so they have to use diesel locomotives to run freight trains (and whatever other odd trains) on the commuter lines.

[@kevinrayner5812]

Didn't BR continue to run the odd train from Epping to Liverpool Street leaving the Central Line at Leyton into the 70s? I remember seeing a photo in a railway publication but I can't find any reference to it anywhere. There was also East Finchley to Mill Hill East. BR locos at least used to operate the Chesham branch in steam days and goods trains into Watford Met station.

[@decimustv4257]

The thought of trains sharing tracks scares me because I think they I am going to have a head on collision :(

[@MLampner]

As always enjoyed your video. I wondered as you didn't address it if the issue with the deep level lines having a different loading gauge than the subsurface and national rail services also impacts the ability to share. In NYC the system I grew up with we have the A Division and the B Division. Again like London's system the older A division often known as the IRT (Interboro Rapid Transit) and the B Division consisting of the BMT and IND (Brooklyn Manhattan Transit and the Independent) have different loading gauges and a as a result an A division train can fit through a BMT or IND line, but the opposite is not true. Oddly in New York, the narrower train is the older system predating the first BMT lines by 15 years. Any way I was curious if that impacts any of the line sharing you discussed.

[@defender1006]

LOL, 'is that clear, then if so I've probably left something out', plus 'I don't know about you, but I'm have trouble keeping up with this?' a couple of crackers there Jago, just keep them coming please!

[@glennharrison7036]

You point out that occasionally, mainline trains share the very same track as London Underground trains. The running rails are all standard gauge so the same width apart ... so no problem there. Certainly down at Richmond, these trains use DC current current. But main line trains use 730 volts DC from that third rail to earth. Whereas London underground trains use +420 volts DC above earth from that third outer rail and -210 volts DC below earth. These are two different systems. How do both sets of trains work on this different system?

In the early 1990s there was a strange accident at the set of points just north of Gunnersbury where the North London and District Lines part ways. A northbound District Line train had just left the station but some idiot switched the points before it was fully across. The front of the train went right and the back end went left. The result was a carriage beached on the point of the Gunnersbury Triangle (a rather nice little nature reserve in the space between the two lines and the Piccadilly Line & Ealing branch of the District). The sides if the cutting are rather steep there and several passengers had to be helped up by the Fire Brigade. Correction: it was 1999 and was blamed on poor maintenance. en.wikipedia.org/wiki/List_of_London_Underground_accidents#Gunnersbury_Triangle

With supposedly tube services being used only 85percent of pre covid capacity (like we were all wedged in), TfL want to reduce some headways , from 1.5min to 2 on Vic , and 2 to 3 mins elsewhereish. It really is bad enough having to wait 4mins for a tube train, and the 5min sunday services are useless as even they get busy. What we had was at least a bit of breathing space on the trains with the better frequencies and Friday evenings from Clapham North going south are still permanent armpit sniffing land until Tooting Broadway
