Hi filth,
Just got Rays email,
London Uderground aren't recruiting direct recruiting direct recruit train drivers any more, they may do again at some point, however, if thats what you want to do, the thing then, is to come on as a station assistant, or any other job on the Underground, and from there apply for a drivers job.
Station Assistant earns good money, plus you'll get a free pass for the Buses and Trains.
Be warned though, its shiftwork, I just got home about 20.00hrs, left this morning at 07.30hrs, and you'll have to travel for your job, eg, whever you live, you may get posted at the other end of the combine, but if you can get in, its worth it.
As a Train Driver, you'd be expected to get the train moving if it breaks down, (which happens quite a lot), learn rudimentary first aid, all the different fire hydrants.
But you get intensive training on all that, Rules and Regs, Train Equipment.
If theirs anything specific you want to know, post back, and i'll give you the best answer I can.
Good luck.
Now-a-days, you have to apply through Transport for London (tfl),
