As a "thank you" to passengers on the Gospel Oak to Barking Overground line who have endured months of disruption whilst electric trains were being set up, TfL are giving a month's free travel on the line.

It will be free for passengers to use the route from August 31 to October 1.

The disruption on the line resulted in service frequencies being reduced from four to two trains an hour earlier this year, and often there were replacement buses instead of standard service.

The bill — likely to be about £2 million — will be picked up by manufacturer Bombardier, who finished the electric trains project 16 months late.

Deputy Mayor of London - for Transport Heidi Alexander made the announcement on Twitter:

Pleased to announce details of a month’s free travel for users of the Gospel Oak to Barking Line this September to say thank you for everyone’s patience whilst we have got the new electric trains up and running. More details at: http://tfl.gov.uk/gospel-oak-barking-trains …

New trains

Following the delays, electric trains have now been introduced on the Gospel Oak to Barking line, about a year behind schedule.

Manufacturer Bombardier had suffered problems with their on-board software, which had caused further delays.

TfL tweeted that the new state-of-the-art trains on the Gospel Oak to Barking route of the Overground are ready, complete with Wi-Fi, Air con and charging points.
