//Appointed in 2016

DEG Signal was appointed as 4LM’s Systems Review Panel (SRP) Chair in 2016.

Over the last few months, our Engineering Director Russell Gell, has been working closely with the 4LM Project Team to review the readiness of the project to move into the system testing phase where the Seltrac CBTC will be controlling the movement of trains between Hammersmith and Latimer Road, a section known as SMA0.5, on the Hammersmith and City line.

SRP authorised the readiness of the project to move into the testing phase in SMA0.5 in September.

// Testing ongoing

Testing is ongoing, with a plan to authorise the system for revenue service in SMA0.5 in the Spring of 2018.
