Three Bridges Depot & Williams Way Substation
The new Williams Way Substation has been built to supply the new Three Bridges depot. 4kA Bonding devices supplied by LCS are on the outgoing feeds to the depot which can be used to bond the outgoing supplies for maintenance.
LCS2 Disconnectors and alternative feed interlocked LCS2 Disconnectors are used to configure and isolate the various depot supplies to minimise disruption during routine maintenance. LCS Marshalling Panels collate the microswitch indication from the LCS2 to interlock with the appropriate Supply Circuit breakers.
The Three Bridges depot, is split into east and west-side facilities either side of the London to Brighton mainline and comprises:
A 5 road, 12-car, maintenance building with the road supplies provided by LCS contactor panels specifically configured for this site. LCS Emergency stop panels marshall all of the emergency buttons from these roads.
11 train stabling and servicing roads, LCS Emergency stop panels marshall all of the emergency buttons from these roads. These signals are then grouped with equivalent signal from other sections of the depot in a master Emercgency Stop Panel
There are 2 two carriage washing machines which have DC electrical supplies fed through Wash Road Panels ensuring that the Washing machines are operated with the DC supply isolated and the tracks bonded.
1 wheel lathe road has its DC electrical supplies fed through an LCS Buffer Zone System ensuring that the Wheel Lathe Depot Earth system is not connected to the Traction Negative.
This depot is due for completion in 2015.
