Looks great in the snow, missing the 455s already!

[@cmeonthemove]

Wow that was some serious arcing! The traction motors obviously didn't like it judging by the way they kept cutting out.

[@gwyneddboom2579]

I don’t think they were cutting out, the sound of the motors was probably drowned out by the sound of rather spectacular arcing.

[@busesinthemidlands]

The train motors keep cutting out because it was having WSP. (Wheel Slip) correct me if I’m wrong.

3rd rail no good in snow!

[@its.jsgino]

That's why third rail at platforms are on the right hand side, not the left That passenger looks intrested

[@joeymandrews]

​@Jahshai I think what : Riley meant was that the third rail are normally situated on the outside of the running rails furthest from the platform. However there are some exceptions. For example, the westbound Central Line platform at Stratford. Seeing as there are two platform faces on both sides of the track, the positive conductor rail would be situated next to one of the platform faces. But in most cases where there is only one platform face, the third rail would be positioned furthest from the platform.

[@dopiaza2006]

@@joeymandrews But that is a 4 rail system with two live rails, right?

[@samb439]

@@joeymandrews oh yes Stratford. The left platform is the one with the positive third rail next to it. But I think I saw parts of the side covered with wooden planks to maybe prevent different paths for the current (I’m not too sure)

Reminds you of how dangerous that 3.rd rail is!

ac overhead has 33x the voltage

[@terrier_productions]

oh.. my.. has a train ever could on fire from a sparking third/forth rail shoe?

[@Dutch3DMaster]

I can't recall it happening with the metro cars in my country, and they are prone to arching in winter conditions sometimes as well. There's a lot of thermal mass up towards the installation from where the pickup electrode is mounted and it would take tremendously long arching to sustain the heat buildup to set things on fire. In this case there's cold air blowing past it and the arching is intermittent, so chances are small. In some cases when arching happened in dry hot weather the chances of that kind of thing sparking wildfires are much, much bigger. That said: this will cause some tremendous damage to the electrode and possibly the third rail itself, and if I'm not mistaking you can definitely hear the difference between AC and DC: DC like I think we are hearing in the video sounds a whole lot more agressive and tends to be capable of doing more damage in shorter amounts of time at the same amount of power than AC is capable off. Long story short: this was an impressive video :P.

[@el1924]

how much voltage goes though the live rail?

[@johnbell3621]

You could get a multimeter, set it to volts, put the black on one of the running rails and put the red on the 3rd rail.

[@Jeagles]

John Bell don’t think you’d have a multimeter (or life) after that

[@dopiaza2006]

@@Jeagles To be honest you'd probably be fine. Even cheap multimeters are usually rated around 600v so would easily take 750 without breaking down. Just don't set it to Amps!

[@samb439]

@@johnbell3621 you’d have to be fully trained first and working as an electrical engineer before doing that. Also you’d want to isolate yourself from ground. Plus it’s not a good idea to do that when trains are operating

[@thegroupofreptiles6823]

In the UK this will be around 600-750v DC

[@train4905]

Awsome

[@kk-transport]

It looked like the train was about to shut down

[@Recroom_troll]

And yall say 3rd rail isn't dangerous

[@Martindyna]

It's lethal and DC as well. Whoever thought of putting lethal Voltage busbar at ground level needs their heads examining. Inefficient for power distribution as well (comparitively low Voltage). Cheap to install though compared to overhead.

[@dopiaza2006]

Nobody (sane) has ever said 3rd rail isn't dangerous. You literally have a live conductor open to anyone to walk up to and touch.

[@Great_WesternTVFan]

Imagine the train actually exploded

[@Househead1200]

An ancient, inherently lethal system. Time they pulled it up and had a rethink.

[@RyanTheHero3]

You think that’s bad? That’s the shit I see from the old 313s WITHOUT snow

Never ride with National rail during the winter.

you know not everywhere is powered by third rail

yeah - some 500Ampere

[@AD-hf1hp]

@@CXensation more apparently. Over 1000.

[@CXensation]

@@AD-hf1hp As you know, the class 455 trainsets have one driving mid motorcar with 4 electric driven axels. The third rail is powered by a 750V DC voltage source. Each electric axel motor consumes 185kW max, which makes for a max power consumption of 4 x 185kW = 740kW total. Ohm's power law P = U x I gives us 740kW/750V = 987A. Which is substantally more than my first guess out of the blue - but less than 1000A 😜 🤓

probably everyone onboard that train died after that
