Contract received from Docklands Light Railway

DB ESG to help Docklands Light Railway improve performance in low adhesion conditions

DB ESG is delighted to report that it has received a contract from Docklands Light Railway Ltd. (DLRL) for its brake system technology. DB ESG will be developing its wheel slide protection evaluation rig (WSPER) to test DLRL’s fleets of B92 and B2007 trains. The wheel slide protection (WSP) fitted to these trains will be evaluated using WSPER to establish the realistic train performance across a range of reduced adhesion conditions. The aim of the testing is for DLRL to qualify the overall performance of the rolling stock in reduced adhesion conditions, to help inform the design of future DLRL fleets and to assist with the planning and implementation of a signaling system upgrade.

WSPER is a ‘hardware in the loop’ simulation tool, used to test the performance of a train braking system in reduced adhesion conditions. By creating realistic operating conditions and interfaces, WSPER makes the brake equipment believe that it is fitted to the train, resulting in the ability to establish the typical train’s performance.

A significant development programme of the WSPER rig will be conducted, to provide additional modelling functionality for the DLRL trains.  This includes articulated train modelling and electro-dynamic brake testing. ESG will be introducing new hardware and software as part of this contract. The development and testing programme is expected to take approximately one year to complete.

Project Technical Lead and WSPER Manager at DB ESG, Stuart Brown added: “This order follows one from London Underground announced last month, for optimisation tests on the sander systems of s-stock vehicles. We are proud of the industry’s interest in our brake system technology and look forward to supporting DLRL, helping them to improve the operation of their trains.”
