The major area for energy efficiency on the railway is the introduction of regenerative braking on electric rolling stock. This can yield major savings of power consumption depending on the system. The new order for trains placed by TfL for the London Rail Concession will feature regenerative braking capability. However the operation of this system will depend on the power supply systems infrastructure being upgraded to cater for this facility.The core section of the East London Line infrastructure being built under the ELL Project will be configured to accept regenerative braking when it reopens. Network Rail has publicly stated its commitment to modify power systems to allow regenerative braking and this will introduce further efficiency savings across London's rail network. The Underground already operates regenerative braking on its more modern stock.
