Striking images of the new Elizabeth Line tunnels taking shape beneath London have been revealed.

With less than 18 months until the Crossrail line opens, engineers are working around the clock to install the overhead power system for the new trains.

The images show engineers installing the cabling and power supply system inside the vast tunnels which run for 26 miles beneath the capital. 

Each Elizabeth line train will draw power in the tunnels from a rigid “overhead catenary system” including an aluminium conductor bar housing copper wire. The bars are currently being installed in 10 metre sections.

More than 1,500km of cable is being installed to supply power, lighting and ventilation systems to the new railway – about the equivalent of 100,000 double-decker buses. 

The main power supply in the tunnels under central London will come from two new bulk supply points, which are being built at each end of the new railway. 

The images, released by Crossrail this week, show work being carried out in the Connaught tunnel in Docklands and the tunnels beneath the River Thames and in Stepney Green.
