What percentage of UK Railways is electrified?
As a result of various electrification schemes across Great Britain, 6,045 km of the mainline railway route is now electrified. This is 37.9\% of all route length. In 2020-21, 179 new electrified track km was added to the network.
Are all trains in the UK electric?
Currently the only trains that could meet this criteria are electric, but only 42\% of track in the UK is electrified and 29\% of Britain’s current fleet is run solely on diesel fuel. These trains will need to be re-engineered or scrapped before they get to the end of their useful life to meet government targets.
Why are trains not electric?
To operate without an external power supply, the train must transport its own energy for propulsion. Traditionally, this was carried along in the form of coal and water (steam traction) or diesel (diesel traction).
How many trains in UK are electric?
Just 8.5\% of freight locomotives in the UK are electric. This lags lamentably behind mainland Europe, thanks in part to gaps as short as two miles in the electrified network.
Why do tube trains have 4 rails?
The fourth rail was chosen, partly as a cheaper option and partly for signalling reasons. As direct current track circuits were to be used to control signals, an insulated return system for the traction current was an effective way of separating the two systems.
Why do we electrify trains?
Electrification eliminates pollution at point of use and offers potential carbon reductions by enabling rail traction to be powered by renewable energy sources. It also reduces dependence on fossil fuels that, in the future, could become increasingly costly due to pollution taxes and shortages of supply.
Why are railways electrified?
Electric trains are significantly cheaper to operate and maintain, as well as being more reliable. Diesel fuel is also significantly more expensive than electric traction, in part because electric trains can recover the huge amount of energy generated during braking back into the wires.
Are railway tracks electrified?
Trains are powered by electricity carried through overhead lines or a conductor rail, sometimes called the third rail. The third rail has 750 volts passing through it. Overhead lines carry 25,000 volts – that’s 100 times greater than the power supply in your home.

When was the first railway electrification introduced in the UK?
Railway electrification in Great Britain began during 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…
Is Network Rail still engaged in electrification projects?
UK rail infrastructure operator Network Rail is still engaged in electrification projects across Britain, including lines in Glasgow, Manchester and London. It is also building and extending new lines with overhead line equipment for Crossrail and HS2, two of the most high-profile ongoing rail projects in the country.
What voltage do trains run on the UK railway network?
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. As at April 2019, 3,736 miles (6,013 km) (38\%) of the British rail network was electrified.
What type of electrical power is used in the railway system?
According to Network Rail, as at 2003, 64\% of the electrified network used the 25 kV AC overhead system, and 36\% used the 660/750 V DC third-rail system.
