The London Underground uses a four-rail system where both conductor rails are live relative to the running rails, and the positive rail has twice the voltage of the negative rail.

Train tracks in UK are electrified so that they can provide power to the electric locomotive our the electric traction motors of the train.
A few early subways used steam engines, but in most existing subways, the trains, tunnel lights and station equipment all run on electricity. Overhead wires or an electrified rail known as the third rail supplies power to the trains.
If there is enough time, run in the direction of traffic toward the end of the platform and use the emergency stairs there. An emergency stop will be issued by the station guard. If there's no time, lie down between the tracks, face down, head in the direction of travel.
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. Nearly half of the UK rail network is now electrified – and more than 30 percent uses a third rail to power the train.
The number of route miles electrified in these years was answered to a written question in parliament. In November 2019 the annual statistics for route miles electrified was published by the DfT and shows that 38% of the UK network is now electrified.
Railroad tracks are private property, not public trails. It's illegal and dangerous to walk on or near tracks unless you're using a designated crossing.
So the answer is yes – it is possible to survive lying under the oncoming train, but it is very unlikely that you could survive that without a major injury. It is a good idea to stay away from railroad tracks. Just by hanging around such places you are putting yourself in danger.
As others have noted, yes it is technically possible, but EXTREMELY inadvisable. Every effort should be made to be safely off the tracks. You would need to lay perfectly flat, and hope the that nothing is hanging that might catch and drag you or pull you under the wheels.
It's IllegalTrespassing onto railroad property, including tracks, bridges, buildings and signal towers, is illegal. Violators are subject to a citation for trespassing. Union Pacific will seek removal from publication any photograph or video that violates this policy.
The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.
Broader gauge railways are generally more expensive to build, because they are usually heavier in construction, use larger cars and locomotives (larger loading gauge), as well as larger bridges, larger tunnels (larger structure gauge).
The Swiss rail network is the largest fully electrified network in the world and one of only eleven to achieve this. China has the 2nd largest electrified railway length with over 70% of the network, after India overtook china having almost 80% of its railway network electrified.
Why are UK trains so expensive? One of the main reasons the price of train tickets keeps rising is the privatisation of rail networks, with every private company striving to make a profit.
The Underground is electrified using a four-rail system, the DC traction supply being independent of the running rails. Planned improvements include new stations, line extensions and more lines with automatic train operation (ATO).
In one study conducted at the BNSF Railway Hobart Railyard in Los Angeles, the California Environmental Protection Agency estimated that residents living near a railyard experienced a higher risk of carcinogen exposure.
When Britain enjoys a summer heatwave, rails in direct sunshine can be as much as 20°C hotter than air temperature. Because rails are made from steel, they expand as they get hotter, and can start to curve this is known as 'buckling'.
