The electrification of South Wales continues to make steady progress with the scheduled commissioning of the independent feeder between St. Brides and Canton substations. It greatly increases the operational and engineering access flexibility of the electrification systems and builds towards further electrification of the South Wales mainline and the Barry Lines. Leeps Ltd is pleased to be working with Network Rail and WJ Project Services to support the approval of the new overhead line and distribution isolation diagrams and instructions.
