Electric trains generally draw power from AC overhead lines. Some DC lines do exist, but they are getting replaced by AC lines. Motors used (traction motors) are generally DC motors.
High-speed-trains usually run on 25,000 volts alternating current (AC), but a few countries operate trains above 200km/h with other voltages, such as 15,000 volts AC in Germany, Austria and Switzerland. Some sections of high-speed lines in Italy and Russia use 3,000 volts AC.

Historically, the 110 V battery located in the main locomotive was the source of dc power for most electrical rail applications. This meant providing light to the carriages required running cables along the full train length.
They now have six hydrogen-powered trains running regularly between different cities in the region, replacing conventional diesel trains in the process. Thanks to a fuel cell, the trains can drive completely emission-free.
The China-Europe Block Train is the longest rail route in the world, having surpassed the Trans-Siberian railway (5,772 miles) and the Moscow-to-Beijing (4,340 miles) train. It is 8,111 miles long (13,000 kilometers), travels through eight different countries, and can stretch three times from Florida to Washington.
