The Gallery | Crossrail power lines installed

Images released by Crossrail show engineers fitting tunnels with a 2x25kv overhead power system ahead of the Elizabeth Line’s opening next year.

The trains, which will pass through 40 stations when the £15bn line is operational, will use power from aluminium alloy conductor bars, currently being installed in 10m sections throughout the tunnels.

Two supply points are being constructed at each end of the line, with autotransformer sites to come in east and southeast London. Two new 21km twin-bore tunnels have been built for the Elizabeth line, which crosses London from Reading and Heathrow in the west, to Shenfield and Abbey Wood in the east.

More than 1,500km of cables are being used to power the new railway. It will be up and running through central London in December 2018, desite news that the first trains are delayed.
