The third rail is probably one of the most difficult dangers to see. It looks just like an ordinary rail, but it carries 750 volts – easily enough to kill you. The DC current that flows through is three times as powerful as your home electricity.

The third rail is usually located outside the two running rails, but on some systems it is mounted between them. The electricity is transmitted to the train by means of a sliding shoe, which is held in contact with the rail.

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.
Amtrak, the national intercity passenger railroad, inherited a 1930s-era 11 kV 25 Hz electrification system from the Pennsylvania Railroad (PRR), which it is slowly modernizing, and has completed two electrification projects on its own lines.
If you touch the rail, you will “stick” to it. The DC current that flows through it will pull you in and not let go until the emergency services are able to switch the power off. Nearly half of the UK rail network is now electrified – and more than 30 per cent uses a third rail to power the train.
Unlike countries like United States, where mainline freight rail electrification is nonexistent, a large percentage of European freight trains are electrified.
Europe's first trains to use batteries as a main source of power have arrived. Hitachi Rail announced last week that 20 tribrid trains—nicknamed “Blues”—are now running on rail lines across Italy. The trains have the ability to switch between battery power, electricity and diesel.
