Europe’s biggest infrastructure project is now in its final stages - all the platform screen doors are installed with testing underway, installation of the overhead power equipment in the tunnels is complete and the new stations are being fitted out with remaining architectural finishes and mechanical and electrical equipment.
 
The new Elizabeth line trains are currently being tested between Abbey Wood and Canary Wharf using the line’s new automatic train control system which operates in the central section of the route. Train testing is taking place in the tunnels at speeds of up to 60 mph. The overhead power equipment has also been successfully switched on in the remaining section between Westbourne Park and Stepney Green which means that the Elizabeth line tunnels are now fully energised.
 
Later this year, the first completed infrastructure will be handed over to Transport for London, who will lead the trial operations and commissioning phase ahead of the opening of the Elizabeth line in December.
