Sunday night saw a first, as an Elizabeth line train entered the Crossrail tunnels under its own electric power for the first time.
The train was previously hauled through the tunnel to Abbey Wood in October 2017 using a locomotive. Sunday’s live test is the first of hundreds of live test runs that will take place throughout the year.
The new train was the first to be driven from Abbey Wood and entered the new tunnels at Plumstead Portal, traveling under the Thames heading for Connaught Tunnel before returning to Abbey Wood station.
Intensive testing of the railway and signalling will now begin to ensure services are ready for the opening in December his year. One train will initially be used for testing in the tunnels before more are gradually introduced.
Earlier this month, Crossrail successfully activated the 25kV overhead lines in a section of the tunnels beneath the streets of London, a landmark moment that ensured this first journey could take place.
A significant amount of work continues to complete all stations on the route as well as bringing together the complicated interfaces between track, power, signalling and trains.
The Elizabeth line is due to open this coming December.
