"A couple of weeks after the first of the new trains came into service last year, a problem occurred when one of the trains overshot its stopping point. Three of the fleet of 54 new trains had entered service, so all three were removed while the braking issue was investigated."
"Since then, engineers have been working to introduce a package of improvements, including braking software upgrades to improve performance under the specific low-rail adhesion conditions experienced during the incident. The changes are now being tested on the manufacturer's test track before further testing on the DLR network."
"We know customers are looking forward to travelling on these new trains, and we will provide a further update in the spring, with the trains being reintroduced by summer. Our engineers, together with CAF and our franchisee KeolisAmey Docklands, have worked tirelessly to ensure they return safely and reliably."
New DLR trains experienced braking problems after entering service, with one train overshooting its stopping point. All three trains in operation were removed for investigation. The issue resulted from multiple contributing factors related to low-rail adhesion conditions. Engineers have developed improvements including braking software upgrades to enhance performance. Testing occurs on the manufacturer's test track and the DLR network, requiring line closures over several months. Passengers will not board these trains until summer, with further details provided in spring. The new trains offer increased space, improved accessibility, real-time travel information, and air-conditioning.
