The batteries are charged via the pantograph either when running under an overhead electric supply or at a specially built recharging facility.

When the electricity stopped, during the running on railway track, the all trains which is running with electric locomotives has stopped. The train will stopped until the power supply start.
The trains have a short range of up to 15 kilometers (about 10 miles) on battery alone, but can recharge as they go, using the pantograph (the apparatus on top of the train which connects it to a power line) or by braking, meaning it can recharge multiple times during a journey. Maximum speed is 160 kph (100 mph).
Railway electrification in Great Britain began in the late 19th century. A range of voltages has been used, employing both overhead lines and conductor rails. The two most common systems are 25 kV AC using overhead lines, and the 750 V DC third rail system used in Southeast England and on Merseyrail.
Electric traction motors often produce electromagnetically induced noise. This high-pitch noise depends on the speed and torque level of the machine, as well as the motor type. Variable-frequency drives use pulse-width modulation, which introduces additional current harmonics and results in higher acoustic noise.
In our world, a catenary is a system of overhead wires used to supply electricity to a locomotive, streetcar, or light rail vehicle which is equipped with a pantograph.
Most overhead railway cables carry a voltage of 25,000 volts (25kV) in order to power electric trains. This is roughly 100 times more powerful than the electricity used in your home.
The majority of modern electrification systems take AC energy from a power grid that is delivered to a locomotive, and within the locomotive, transformed and rectified to a lower DC voltage in preparation for use by traction motors.
Power Sockets: UK and European power sockets are available at every seat on newer trains. USB sockets are available in Business and Standard Premier on these trains. Older trains have UK and European power sockets in coaches 5, 14, and all Business Premier and Standard Premier coaches.
As you know 25kV is globally accepted voltage level for electric locomotives. Reasons to choose 25 KV instead of 240/415V is that for less voltage like 240V or 415V, flowing current increase to dangerously high value and counductor/Line could be burnt out.
The life expectancy of diesel-electric and electric locomotives is expected to be similar—about 25 years. Both types of motive power are subject to technological obsolescence.
The Federal Railroad Administration does not currently set any limits on train lengths – and also doesn't regularly track train lengths or their associated risks. That has allowed freight railroad companies to occasionally operate trains up to 8 kilometres (5 miles) long.
NYC No. 999 4-4-0 was quite the speed demon for its time. The first locomotive to travel over 100mph, 999 hauled the Empire State Express and hit a world record speed of 112mph!
