Transport for London (TfL) has taken a step in its search for a manufacturer to design and build a new generation of DLR trains, by issuing an Invitation to Negotiate.
Four pre-qualified bidders – Alstom Transport, Bombardier Transportation, Construcciones y Auxiliar de Ferrocarriles and a consortium, consisting of Siemens , Stadler Bussang and Stadler Rail Valencia – can now proceed to the next stage of the formal procurement process for the new trains, which will come into service from 2022.
TfL will replace two thirds of the existing trains, some of which are 25 years old, and order an additional ten new trains to provide more capacity to the network.
They will feature on-board real- time information, air-conditioning and mobile device charging points for the first time. The extra trains takes the total capacity increase to 30 percent for the DLR network.
The contract to build the new trains will be awarded in autumn 2018.
The main difference is that instead of fleets of 2 or 3 cars, these will be similar to the modern trains, with a fully walk-through design.
Currently, around 20% of the length of a DLR train is doors, while the average for most metro-grade services is 30% for doors. The design change to fully walk-through carriages also releases more space for doors, so that people can get on and off faster.
The redesigned trains should be able to carry about 10 percent more passengers than the current trains.
