Alstom Widnes - Arrival Road Sidings and Electrification
The Challenge
Alstom needed to expand its Widnes depot with a new arrival road and departure connection into Ditton Sidings. The project required integrating a live electrical feed from Network Rail infrastructure, constructing a 30m on-load/off-load slab with sunken rails for articulated trucks, and adding a lorry turning circle, walkways, a new side road, and lighting.
The complexity was heightened by the fact that part of the works had to be carried out beneath existing overhead wires, demanding meticulous isolation planning and coordination with Network Rail route planners. Approval processes, including a MORF application and updated electrical isolation diagrams, added further technical challenges.
Our Solution
RCA delivered a comprehensive design-and-build solution that combined precision engineering with robust safety planning. Key elements included:
Integration with Network Rail Infrastructure: Ensuring compliance and safe connection to live electrical feeds.
Specialised Construction Features: A 30m slab with sunken rails for articulated trucks, plus turning circles and walkways for operational efficiency.
Advanced Planning: MORF application approval and detailed isolation diagrams to meet Network Rail standards.
Safety-First Execution: Careful scheduling of overhead line isolations and coordination with route planners to maintain depot operations.
The Result
The project was completed in just eight months, with minimal disruption to depot operations. The new arrival road now provides Alstom Widnes with greater flexibility, enabling trains to arrive on flatbed lorries ready for upgrades. This solution has enhanced operational efficiency and set a benchmark for complex electrification projects in live rail environments.
