London Underground tests technology to tap waste energy from train brakes - Railway Technology
London Underground (LU) in the UK has carried out a five-week trial of a new inverter technology, which recycles unused energy from the brakes on trains.
The trial conducted at Cloudesley Road substation on the Victoria Line showed that it could save London enough electricity to reduce the Tube's energy bill by 5%.
LU noted that in the first week of operation, the new technology recovered enough electricity to power a large underground station such as Holborn for more than two days a week.
