Transport for London (TfL) has unveiled the first of the new state-of-the-art Elizabeth line trains.
The new train was unveiled at Bombardier Transportation’s test track in Derby.
In total a fleet of 66 new trains will operate on the TfL-run line, serving London’s West End, City and Docklands and running from Reading and Heathrow in the west across to Shenfield and Abbey Wood in the east, through 40 accessible stations.
The new Class 345 trains will enter service in May 2017 on TfL track between Liverpool Street and Shenfield. The first trains will initially be seven carriages or 160m long to fit existing platforms at Liverpool Street.
Eventually nine carriage, 200m long, trains capable of carring up to 1,500 people and will be introduced from May 2018, initially running between Heathrow and Paddington.
TfL said that all the trains would feature walk-through carriages, air conditioning, CCTV for passenger security and real-time travel information.
Each train is constructed from lightweight materials and will regenerate electricity back into the power supply when the train brakes, using up to 30% less energy than conventional trains said TfL.
Deputy mayor for transport Val Shawcross said: “These state-of-the-art trains will play a key role in London’s future – helping to deliver a modern, world class transport system through the new Elizabeth line and enabling London’s transport network to cope as our population rises.
“Alongside the new and modernised stations they will serve, the new trains will transform travel across London and will make life better for millions of Londoners.”
The new trains are being built and tested at Bombardier Transportation’s UK site, providing 760 UK jobs and 80 apprenticeships.
TfL said that the first train is to undergo a rigorous testing programme in Derby and from next month at the Old Dalby test centre in Leicestershire. It said that the trains would be extensively tested to ensure they meet its high safety, performance and reliability requirements.
Testing will involve being loaded with over 100t of weight to simulate being full of passengers, and will include taking a complete carriage to a climatic chamber to ensure passengers can remain comfortable at temperature extremes.
Once trials are completed, testing equipment will be removed from the first trains and the interiors of the trains will be completed with seats and moquette seat-covers before delivery for passenger service.
