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.

Trains in the UK are powered by a mix of electricity and diesel fuel.
The UK Government has announced that diesel-only trains will be phased out by 2040. Currently, 29% of the UK's fleet is diesel and the move has been received positively by campaigners.
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.
Today, most trams use electrical power, usually fed by a pantograph sliding on an overhead line; older systems may use a trolley pole or a bow collector. In some cases, a contact shoe on a third rail is used.
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.
There are five lines in the UK which allow for high-speed rail travel. On four out of five lines, the maximum speed is 125mph, while the purpose-built HS1 line allows for speeds of 186mph.
Lumo is a 100% electric train service, travelling exclusively down the East Coast of the UK between London & Edinburgh, calling at Stevenage, Newcastle & Morpeth.
Electricity is generated by power stations in the form of high voltage alternating current (AC), but Underground trains operate using a Direct Current (DC) system.
Being one of the busiest railways, it offers more than 25 train operating companies with thousand destinations. Providing passengers excellent facilities and service onboard British trains feature high-speed comfort during a train journey!
Biodiesel & Renewable Fuels: Traditionally, locomotives have run on petroleum diesel fuel, but railroads are now using renewable diesel and biodiesel blends to power them. Both renewable diesel and biodiesel are made from renewable energy sources and don't rely on fossil fuels.
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.
American railways were also built on a wider gauge (the distance between the rails), which allows for larger and heavier trains. As a result, American freight railways are much more efficient than their European counterparts, carrying almost three times as much cargo per mile of track.
Contact wire is generally built in zig-zag to reduce the wear on pantograph slide. When the train is running at a high speed, the contact wire has to face the extreme working environment such as vibration shock, temperature difference, environmental corrosion, mechanical friction, and arc ablation [48].
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.
