Transport for London (TfL) today announced the four bidders shortlisted to supply new rolling stock to run on new London Overground routes out of Liverpool Street station and to replace current two-car diesel trains on the Gospel Oak Barking route.
The successful bidder, which will be announced in Spring 2015, will be asked to supply 39 new four-car, electric, metro-style trains to operate high-frequency, high-capacity suburban services in and around London as TfL continues its programme of investment in this highly successful urban railway.
Thirty-one new trains will operate on routes recently devolved from the West Anglia franchise to TfL which run between Liverpool Street and Enfield Town, Cheshunt (via Seven Sisters) and Chingford as well as the Romford to Upminster route.
Eight of the electric units will be allocated to the Gospel Oak to Barking service to replace the current two-carriage diesel trains and alleviate congestion as well as provide a more environmentally friendly rail service.
Mike Brown, TfL's Managing Director of London Rail, said:
'New and reliable trains have been a key contributor to the huge success of London Overground since TfL took over the management of Silverlink Metro services in 2007.
'Our customers have now come to expect something better from London Overground and that is why this competition is so important to take our service on the Overground to the next level.
'We welcome the wide international interest from the rolling stock market in bidding for this order and look forward to engaging with the chosen manufacturers to define a standard that will set a new benchmark for TfL for many years to come.'
London Overground achieved one of the UK's highest scores for passenger satisfaction (91 per cent compared to a national average of 82 per cent) in the results of a survey published last month by independent transport watchdog, Passenger Focus.
The railway also came in at number two in Network Rail's performance and punctuality tables for the past year to June 2014 with 96.1 per cent of its trains reaching their terminating station within five minutes of their scheduled arrival time.
This compares with the national average of 89.7 per cent.
