Catenary-free solutions for tramway systems

[@nuucha]

I am in Rio and saw that trams have no overhead supply lines but there is a third conduit rail integrated in the ground. I was curious how does it work without electricuting pedestrians. This video helps to understand how the technology works

[@lohphat]

2:06 "brake" not "break". I would hope the trams don't break easily. 😉

[@SkysTrains]

look at ottawa's alstom trams, theres your answer :D

[@GlitchUnpatched]

honestly, alstom should pitch these to the city of vegas, since before going loop crazy, they were planning on putting in light rail, but the casinos didn't want the visual clutter of catenary wires. a solution like this could lead to a dedicated light rail line going through the strip, connecting the downtown the airport and the expected high speed rail line!

[@TheRandCrews]

Would something akin to a light metro would work? I know they have the monorail, not much for expansion but if they had something like third rail running or even linear enduction that the Skytrain and it’s derivatives run tho they are elevated lines but not heaving capacity as actual metros and no wires. Cause looking how wide the strip is with many car lanes there are going to a street level tram seems dangerous

Incredibly Superb....👌👌👌 The future of Mobility is now......

[@BalaMani-72]

no audio for the video?

[@Bobrogers99]

My main concern would be the initial cost of the system. This video suggests two variants - a continuous supply from the third rail as the tram moves along, or recharging at each stop.

[@0ejder0]

It might be cheaper due to cost of overhead wire towers and their instalation. The rail installation is already happening, adding a third rail and some cables with electronics can be considerably cheaper then erecting towers every couple meters

Interesting Technology ❤️✨ Need This In Kolkata,India🇮🇳

[@saubhagyashukla6081]

I request to Alstom to put proposal for this technology in front of Indian government to be used in India 🇮🇳

[@jasonmascarenhas5177]

Doubt over here. We are in a metro construction spree though

[@allancoelho6905]

It is in fact safe, we use it on Rio de Janeiro's tram lines and so far no accidents

Choo Choo: I'm a train and I approve this video :D

[@Steinstra-vj7wl]

What is the top speed with such ground feeding system? Also wonder if this ground feeding power supply still works when ice and snow are lay on top ?

[@allancoelho6905]

About 20km/h or 30km/h, it's a tram, what did you expect? It's suposed to be slow

[@Tamwyn107]

@@allancoelho6905 there are Trams which have a speed of 100 km/h and in my home town even the old M-Wagen trams travel 70km/h

[@allancoelho6905]

@@Tamwyn107 I'm talking about Alstom Citadis trams, those who use the system mentioned in the video, I've only seen they being deployed on heavily dense areas, surely there are trams that operates like trains but for the system described in the video, that is not the case

[@ivanxy996]

Most trams (in Europe) has a max. speed of 70 (maybe 80) km/h, but in built-in areas (as other vehicles) they limited their speed to 50 km/h (for safety reasons). But these with overhead wires.

Can it work when it rains?

[@markylon]

WHAT DO YOU THINK? BE A BIT SHIT if it STOPPED everytime it rains. YOU MUPPET

[@davip8269]

Yes. Rio de Janeiro, Brazil use this system. A video during a rainy day: kzbin.info/www/bejne/qJi1e3WLjKmjoqs

[@My-Opinion-Doesnt-Matter]

​ @davip8269 thanks, do you know how are they preventing the short circuit when the third rail turns on in a puddle?

[@kalpeshwani8520]

Can't this be a continuous process while in motion.... Identified signal Charges only railways else not ...... Swipe cards charging on ......off

[@Michael_NV]

Very nice video and solution. I hope you substitute the supercaps with real battery nowadays.

[@markylon]

You would have thought ALSTOM would know the difference between BREAK and BRAKE. When the tram BREAKS. NO NO NO WHEN THE TRAM BRAKES. How shockingly embarrassing that ALSTOM don't CHECK THE fine details. I bet they do the same when it comes to their standards of safety. SHAMBLES!!

[@ivanxy996]

They are a french company tbh

[@markylon]

@@ivanxy996no excuse. They're global

[@ivanxy996]

@@markylon True, they are an international company, but compared to a regular French (or frenc company) they have quite good english. Most Frenchman can't speak english, and even if they can they won't, because they are to stubborn (cause they don't want to speak in their largest nemesis's language who built the largest and strongest colonial empire (instead of them).

[@markylon]

@@ivanxy996You would think that a global company dealing with Trains and all things safety would be able to spell BRAKES correctly. It show's lack of attention which means what else are they not paying attention to.

[@muhammadhafiz_h4]

Johor Bahru and Kuching in Malaysia should really look into this instead of using CRRC's ART gadgetbahn

Un tram sur batterie électrique... ça fait super gadget je trouve.

No one of them practical.

[@davip8269]

No? So I suggest you take a look at Rio de Janeiro's Light Rail System, which has been working really well with the catenary-free system since 2016. kzbin.info/www/bejne/qJi1e3WLjKmjoqs
