TfL ‘pushing hard’ to get new trains for Barking line

SOME of the first trains ordered for London Overground more than a decade ago could soon be running on the Gospel Oak to Barking line, as the timetable for introducing new units remains blurred.

Electrification of the route was affected by a number of problems. The work started in June 2016 but was not complete until January last year, and the introduction of electric Bombardier Class 710 units should have followed within a couple of months, allowing the diesel Class 172 units to be progressively cascaded elsewhere.

Although the 710s have yet to enter service the cascades have now started, and two 172s have already moved to West Midlands Trains. The other six will stay with TfL until March at least, as their lease has been extended.

The delivery of the 710s has slipped repeatedly. Transport for London told Railnews: ‘The delivery date has continued to be put back by Bombardier. We are pushing them hard.’

The line needs six daily diagrams, and so all the available 172s are used during the week. Weekend services have been reduced so that the units can be maintained on Saturdays and Sundays.

Meanwhile, at least one of the Class 378s built for the original Overground network in 2008 and 2009 is set to be drafted in as a temporary measure, and clearance tests have been under way since the turn of the year.

London Overground general manager Rory O’Neill said: ‘We are sorry for the continuing delay to the introduction of the new fleet of trains on the Gospel Oak to Barking line. The manufacturer, Bombardier Transportation, have advised that they need more time for software development.

‘We share our customers’ frustration and continue to push Bombardier to do everything they can to allow us to bring the new electric trains into service as soon as possible. We are working with Arriva Rail London so that driver training can start as soon as the software issues are resolved.

‘Given the continuing delays we are now exploring the option of modifying Class 378 trains for temporary use. There are a number of considerations that need to be resolved before we can confirm whether this is possible. We are testing a modified train on the line and expect to make a decision later this month. It would operate alongside the existing diesel trains.’

Railnews has invited Bombardier to comment.

Services on the 22km route across the north eastern London suburbs were badly disrupted on 11 January, when one of the six diesel units failed at Crouch Hill.
