The new four-car trains have walk-through carriages, air-conditioning, USB charging points, free Wi-Fi, live information screens and more wheelchair spaces. They can carry almost 700 people - double the number of the old two-car diesel trains that had been operating on the route. They are also much better for air quality and the environment.
Services now run every 15 minutes for most of the day.
For those of you who were caught up in the delay in bringing the new trains into service, we would like to thank you for your patience.
The Mayor of London, Sadiq Khan, has secured a month of free travel on London Overground's Gospel Oak to Barking services. This is being funded by Bombardier Transportation which makes the new trains.

Web credit is only available for customers with an Oyster Travelcard valid for longer than one month because Oyster cards can only hold up to £90 pay as you go credit. Payment as web credit is the best way to make sure customers get the pay as you go refunds they are due.
Also, Travelcard customers who don't use the pay as you go credit on their Oyster card won't be able to cash it in until their Travelcard has expired, whereas any web credit received can be cashed in as soon as it's in their online account
Refunds will only be made in the ways outlined above. We will not issue cheques or give cash refunds.
