The first of the new DLR trains has returned to passenger service after modifications resolved problems that led to the trains being withdrawn shortly after they were introduced last year.
Three of the new trains entered service in September 2025 but were withdrawn shortly afterwards after a performance issue was identified on one of them during low-adhesion conditions.
Transport for London (TfL) and the manufacturer, CAF, have since modified the trains and carried out an extensive testing and assurance programme. The changes include alterations to the braking system and the installation of equipment intended to improve the grip between the wheels and rails. TfL has also introduced measures to reduce the effects of low adhesion at key locations around the DLR network.
After completing testing in a range of operating conditions, the first train has returned to passenger service on the Stratford International to Woolwich Arsenal route.
TfL is currently working with CAF and its suppliers to finalise the full rollout plan for the remaining 53 new trains, with further details to be confirmed in due course, but said that the number of trains in service will increase gradually through the controlled introduction of additional trains.
Stuart Harvey, TfL’s Chief Capital Officer, said: “We’re pleased that the first of our new DLR trains has returned to customer service following the completion of a thorough programme of modifications, testing and assurance.
“I apologise for the delay in reintroducing the trains, but am pleased this marks an important milestone in delivering a modern new fleet for the DLR.”
The new trains have walk-through carriages, air conditioning, live travel information and charging points for mobile devices. Each train also has three multi-use areas and three dedicated wheelchair spaces.
Their walk-through design will increase passenger capacity by around 10 percent compared with the trains they are replacing.
The fleet will eventually replace the DLR’s oldest trains, some of which have been operating for more than 30 years. TfL says the additional capacity will help support new housing and employment in areas including Stratford, Woolwich Arsenal, the Royal Docks and the Isle of Dogs.
