The Northern Siding Package is part of a wider £100m scheme of improvements at the DLR Beckton Depot. The vision, overall, is to create a new maintenance facility and associated infrastructure.

RT-IS is assisting Buckingham Group in a £35m project to deliver facilities for new trains on the Docklands Light Railway (DLR).

Beckton Depot plays an important part in the daily life of the DLR. It is the primary maintenance depot for all trains on the service, having taken up this duty from Poplar – where the DLR headquarters is based. Beckton has already seen a range of improvements, added between 2005 and 2006.

However, further work has become necessary to cater for new circa 86-metre trains. These trains are the equivalent of about three of the current fleet coupled together. Overall, 43 of these trains have been ordered by Transport for London. These will, along with the current B07 units, replace the older fleet of B90, B92 and B2K models and make allowance for projected growth on the service – improving capacity by anything up to 30 per cent.

The scope of works is extensive. New stabling roads, additional track, new switch and crossings units, platforms, walkways, lighting, communications and signalling are required – and RT-IS is assisting Buckingham throughout, including with IRSE-accredited staff.
