How do UK trains get electricity?

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.

Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a sliding pickup shoe.

Certain electric traction systems provide Regenerative brakes. The energy generated by the train is converted into electricity and return it to the power system that is available to be used by other trains, or to the utility grid in general.

Although commonly called diesels, the locomotives actually are electrically driven. The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles.

The reasons for this are varied: from the privatisation of the rail industry to the rising cost of infrastructure. The UK does not have fixed rates like other European countries such as France, which can result in flight tickets being cheaper than a regional train journey in the UK.

If China is the largest exporter of rail technology in the world, its neighbour Japan is certainly the most technologically advanced manufacturer on the market. Having launched the first class of bullet trains in 1964, the country has continuously updated its models according to the latest technological advancements.

The engine for maglev trains is rather inconspicuous. Instead of using fossil fuels, the magnetic field created by the electrified coils in the guideway walls and the track combine to propel the train.
