is it only 750? the current must be huge then... i know the idea for transporting power is to have a really really high voltage and a low current so that there is the least ammount of heat produced therefore not wasting energy. but i suppose the gage of the live rail must have a low enough resistance to not have to do that?
weird
It's cheap to install, the live rail is just a standard rail used to conuct the power. The current is usually 3000Amps and you have sub-stations about every 10 miles.
Here you go.This is what it states for the AC/DC 3rd rail.Believe me as i have worked on the track with these live rails and it is possible to be killed by p155ing on the live rail
the rule has generally been that AC is used for longer distances and main lines and DC for shorter, suburban or metro lines. DC gets up to 3000 volts, while AC uses 15,000 - 50,000 volts.

its not as cheap as you think to install the 3rd rail for electric and there is a hell of alot involved.
The 3rd rail isn't a standard rail it is a bigger rail suspended on ceramic pots to avoid the electric going to the ground.
I have seen what the burns are like on someone who has be electricuted by the 3rd rail and you can actually survive it depending on how you have actually touched the 3rd rail
if you want to know what the 3rd rail can do don't try this.
About 8 years ago i was working for a contracting rail company and we were working a night shift at Raynes Park.While carrying the kit up to the track someone dropped a gennie onto the rail and you should of seen it fly and it was like bonfire night.You never seen a group of trackman run as quick in your lives

yea but its not volts that kill,whats the current that flows through them.???
any part of your body that touches the 3rd rail whether its a constant flow of p155 or one foot on the 3rd rail then you will be electrocuted by it
We were always told that when working on the railway and there is a 3rd rail then we are to take it that it is always live and thats even when the power is shut down for maintenance work

i used to hang around with someone who managed to wander onto the rail when he was younger. he lost a leg because of it and had bad scars from the burns.

my mate is a trackie now... on sunday when we were both out on a train, we see all this graffiti and there was this one bit that could have only been done by some network rail workers. it was written on a bridge and it said "we dont like Brown!!!.......Paint!" lol.. then a bit further down it said "f//k trackies" lol and i thought the only ppl who call trackies are trackies hehe
when or if we work on lines with the 3rd rail during the day we have a plastic sleeve that fits over the 3rd rail and we use specially insulated tools, but you always fine someone will put a foot or go to put a foot onto the 3rd rail to get more leverage on a spanner.

probably someone who got the sack and holds a grudge but no matter how secure you make the boundaries then people will always tresspass.
We had a very near miss yesterday where someone drove over a private crossing.They stopped and opened the gates but never bothered to use the phone to get permission from the signalman to cross.
As they just cleard the up main a 125 came hurling round a corner at 70mph.How the hell the train missed the car we don't know.The train took 1/4m to stop.Once the car was clear from the crossing the passenger got out and rang the signalman to say what happened.I wouldn't like to have the bill for making that train stop and end up late.
