Continuing our ongoing works on the East London Line, Antagrade were engaged to support the additional berthing requirements at Silwood depot to allow train capacity increases in line with the Mayor of London’s manifesto.

Tasked with installing and testing the traction power system upgrades our workscope included the installation, testing and commissioning of a new modular DC switchboard building and its integration into the existing substation at Canal Junction. As well as delivering the ETE works, Section Proving and Short Circuit testing, we provided the system protection study and designed and installed the substation’s new frame leakage protection.

The new substation module feeds the sidings with DC traction power via  a pair of controlled track switches and eleven trackside isolators, all of which were installed, tested and commissioned by Antagrade. All traction cabling – main feeder cables and conductor rail jumpers, negative bonding and return was  laid and installed by us.

The Silwood project demonstrated Antagrade’s core strength as a flexible single-source supplier of design coordination, installation, testing and commissioning services for all elements of the traction power system.
