The Docklands Light Railway (DLR) in London's East End underwent major works to upgrade and expand the network, enabling it to carry three-car (six coach) trains. Working in conjunction with Arup, we provided rail engineering services for the detailed design of stations and supporting structures. Taylor Woodrow was awarded the design & build contract for this part of the project, officially known as Provision of Three Car Enhancement Works.

At project tender stage, we provided full design support including the development of a number of innovative procedures for minimising the strengthening of structures. These included undertaking strain gauging and laboratory testing of a weld improvement technique.

The DLR is an extensive automated network, running from Stratford in London's north to Lewisham in the south, Tower Gateway in the west to London City Airport in the east. It opened in 1987 and includes 70 bridges and viaducts, which required modifications and some strengthening. Bearings and shock transmission units have been replaced and changes made to the permanent way.

Various modifications were made to the network's stations to enable them to serve the longer trains., and we designed one new complete station — South Quay. We also designed a new grade separated viaduct for Delta Junction. A new viaduct was also constructed at Canning Town Junction. Our responsibilities included Category III checking of Arup designs, and geotechnical engineering.
