Grove Park Berthing Depot






Jan 2017


10 weeks



Grove Park Depot was identified as the preferred location to undertake PRM Modifications on Class 465/0 and 465/1 fleets.

This would see 93 x 4 car units rotate through Road 9 as from September 2016 until May 2018. In order to achieve this, it was required that the isolation arrangement and traction supply for Road 9 was taken under the control of the depot operator at Grove Park and not the Electrical Control Room Operator (ECRO) located at Lewisham (ECR).  Installation of new safe isolation system for Road 9 was to allow the switching of traction supply to Road 9 by the depot operator at Grove Park. In addition there was a small building extension and the installation of a new roller shutter.
