TfL Celebrates Re-Introduction of First Modernised DLR Train

Transport for London (TfL) has celebrated the re-introduction of the first of its newly modified Docklands Light Railway (DLR trains) to customer service.

The train, which is the first of 54 set to be gradually be introduced to the network, has undergone a comprehensive testing and assurance programme, and will be closely monitored going forward.

Each of the newly-reworked trains include spacious walk-through carriages (increasing capacity by 10%), live travel information, air conditioning, enhanced accessibility features including three multi-use areas and three dedicated wheelchair spaces, and mobile charging points.

The new trains, which were withdrawn from service in November 2025 after an issue affecting train performance in low adhesion conditions was identified on one train, will ultimately replace the DLR’s oldest trains, some of which are over 30 years old.

Following their removal from service, TfL and manufacturer CAF investigated the issue and developed a solution to the identified issue, and a number of enhancements have now been made in order to improve train performance in low adhesion conditions following extensive testing and assurance work, including changes to the trains’ braking systems, the installation of equipment to improve grip between the wheels and the track, and additional measures to reduce the impact of low adhesion conditions in key locations across the network.

With both these modifications and a comprehensive testing regime completed across a range of operating conditions, the first train has now returned to customer service, with the phased reintroduction of the fleet now beginning on the Stratford International to Woolwich Arsenal route.

The number of trains in service will steadily increase through the controlled introduction of additional trains, and TfL is currently working with both CAF and its suppliers to finalise the full rollout plan for the new trains, with further details to be confirmed in due course.

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.

Safety is always our top priority, and we took the decision to remove the trains from service as a precaution while we worked with CAF to investigate the issue and implement a solution.

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. As we begin the phased reintroduction of the trains, customers will start to benefit from more spacious and accessible journeys, while we continue to monitor performance and introduce further trains into service.

The new DLR trains form part of a wider programme of works backed by 257 million GBP of funding through the Ministry of Housing, Communities and Local Government Housing Infrastructure Fund.
