Are all modern trains electric?

No modern train uses a diesel engine to power their wheels directly. They're used as generators to power electric motors. So the only difference boils down to where the electricity comes from. And even in the most train-friendly countries like France and Japan, huge sections of the network are not electrified.

Diesel electric, electricity or steam power are the three major fuels used by trains. As it was in various other sectors, steam power was also used in the beginning days of railroads.

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.

Only 10% of British freight trains are currently hauled by electric locomotives. However, an electrification programme of 40 route miles per annum for 20 years could deliver the opportunities highlighted by CILT.

Electric railways began in Great Britain in 1883 and the first EMU ran on the Liverpool Overhead Railway in 1893. In the early 20th century, systems were developed where all the motors on a train could be controlled by a low voltage signal from any cab.

Trains in the UK are powered by a mix of electricity and diesel fuel. According to Network Rail, nearly half of the UK rail network is now electrified – with more than 30 per cent of the stock using a 'third rail' to power the train.

Many trains intersperse multiple locomotives throughout their lineup to increase and distribute the power. Besides steam- and diesel-powered locomotives, many modern trains operate solely on electrical power. They get the electricity from a third rail, or electrical line, along the track.

Railway electrification stands at about 37 percent of the global track length in 2018 (based on International Railway Union [UIC][1] data); this percentage has been growing over the last two decades by amounts that vary widely from year to year.

Some locomotives collect electricity from overhead cables, while others take power from a third “live” rail on the track. It is very expensive to build the lines or rails that carry the electric current, but electric locomotives are cleaner, quieter, faster, and more reliable than steam or diesel engines.

Most of the lines emerge on the surface outside the Central London area. The oldest trains currently in service on the Underground are 1972 Stock trains on the Bakerloo line. The Underground is electrified using a four-rail system, the DC traction supply being independent of the running rails.

Most countries have a freight decarbonization goal. These typically include shifting from road to rail and also electrifying rail (IEA, 2019; OECD/ITF, 2021). This model shows that the rail freight industry could expect to see a positive net present value and emissions reductions globally through electrification.

The decision not to procure new diesel trains had already been made in 2020. As soon as trains have reached the end of their economic life, they are now to be replaced with battery trains. Trains that are theoretically still operational are to be used on non-electrified lines during the transition.
