How about very high pressure steam which includes degreaser and deicer sprayed in front of the wheels when slippage is detected. This should clear the rails of most contaminants for several hours assisting the following trains and deal with ice and snow as well.

Liz is so beautiful that it's hard to concentrate on the subject at hand the moment that she appears on camera.

@Abitibidoug 7 лет назад

My thoughts exactly! I liked seeing her as much or more than the interesting content of a one of her shows about wildlife in India.

@shaheedpetersen6231 4 года назад

Spot on. Not only intelligent, but the looks to match. Gorgeous.

Thanks liz

Yes, let the piss taking stop! train drivers can cope with this and do a great job keeping everything safe, but yes there will be a few mins delay here and there!

@smeghead666 10 лет назад

The reason it's still a joke is because we have one of the most untimely and worst kept rail systems in the world along with ironically being one of the oldest yet we still can't manage what are silly basic things which makes them a joke. Leaves were there last year, they'll be there next year, it shouldnt be too surprising

@tcpgblizzard 10 лет назад

It is far from one of the most untimely and worst kept rail systems in the world . If you have ever been to S.America, Africa, Asia or Arab countries then you would see how good ours is in comparison. The British ones are pretty bad compared to Western countries though, so in that sense you are right.

@smeghead666 10 лет назад

***** Quite right, I should've amended t to the western world. But hey at least on those trains you can always escape the crowding and get on the roof :).

No we need to get off the land and use the sea as we are an island ekranoplwns are the way bto.go

Why not spray the wheels with some liquid rubber as a coating, Once the leaves have gone away ( Next day) the rubber would wear away pretty quickly. Another tough coating would be silicone spray, which repels dampness anyway. Might give a much quieter ride too, outside each station have spray guns with huge tanks of rubber or silicone , that are tautomatically riggered as the train rolls out ...when the train leaves (excuse the pun) the stop it automatically gets a coating of spray, At the next station stop process is repeated, Only needed in the Fall. why would something like this not work. Let's face it they are mean and do not want any extra expense it costs THEM nothing to have trains delayed, it isn't in their interest to solve the problem.

@57305northernprincess 10 лет назад

we have a train called Rail Head Treatment Train (RHTT) which sprays water at high speed

@beachfrontal 10 лет назад

***** would I be right to ssume you meant " at high PRESSURE "not a 125 train used to apply the water right.

@uhFrex 10 лет назад

Problem with that is the rubber would get caught in the wheel arches and breaks, or if one side failed it could potentially cause a massive crash.

@illusiondee 10 лет назад

would it help if trains have ABS?

@neilmcmahon 10 лет назад

ABS only allows the change the direction of steered wheels without them losing traction. ABS does not stop a car quicker. On a slippy surface the braked wheels would just not lock and would continue to roll to a stop much farhter on

@AngusDuncan 9 лет назад

They do, ABS came from the railways. It's called Wheelslip Protection (WSP) and most modern trains are fitted with it, although there's a number of strategies that drivers can use that are just as (if not more) effective at preventing lock-ups and slides.

@seyidon7809 3 года назад

Can someone help write out the very first line of her statement. Research has shown that ........ ........ leaves are actually sucked under the train

@superfluidity 3 года назад

soggy, slippy

@jayrap94 10 лет назад

but wouldn't a modern train have abs like a modern car? sure it would still be a longer stopping distance but not quite as long as a lock up like that right?

@jayrap94 10 лет назад

TheCamshafter ah ok - I just googled "do trains have anti lock brakes) just before I read your reply to which the answer seems to be no. Hmm, I guess I'll be looking out for lock-ups next time I need to use a train ;)

@mole259 9 лет назад

Technically trains have a similar system, it's called WSP wheel slide protection, which helps to avoid wheel locking and ultimately severe wheel and rail damage but ultimately as mentioned it's steel on steel not tyre on tarmac
