A trial that uses the latest technology to collect waste energy from the London subway train brakes has captured enough power to run a large Underground station - opening the way for significant savings across the Underground network.

London Underground used the new 'inverter' system at the Cloudesley Road substation on the Victoria line for a five-week trial, and in just one week of operation, the new technology recovered enough power to run a station as large as Holborn for more than two days per week. The results indicated that 1 Megawatt hour (MWh) of energy can be captured per day - enough to power 104 homes per year.
