New images released by Crossrail show how work continues under London to install the overhead system for the Elizabeth line.
The pictures show how each train will draw power in the tunnels from the rigid overhead catenary system’s aluminium alloy conductor bar, which houses copper contact wire. These alloy bars are currently being installed in 10 metre sections.
A dedicated team of engineers is working around the clock to install the 2 x25kV overhead traction power system.
Over 1,500km of cable is being used to supply power, lighting and ventilation systems to the new railway.
The main power supply in the tunnels under central London will come from two new bulk supply points and their associated autotransformer feeder stations which are being built at each end of the new railway along with autotransformer sites in east and south-east London.
