WebThere are two main problems with third rail that make it unsuitable for high speed operation. The first is that third rail systems have very small clearance between the third rail and ground, limiting operation to relatively low voltages, typically 750V, but can be as high as 1200v, while overhead line equipment is commonly run at 25kV, although some systems … WebWe have the largest third rail network in the world, powering electric trains, and it’s mostly found on tracks in the South East of England. When we talk about the third rail, we mean the live rail which provides electric power to a train through a conductor placed alongside the rails.
