Norwich Trowse MDU

EV Charger Installation for Network Rail

Overview

EWG was commissioned to deliver a full-scope installation of a 22kW AC dual electric vehicle charger at Norwich Trowse Maintenance Delivery Unit (MDU). The project supported Network Rail’s sustainability initiatives by introducing EV infrastructure into their operational site, while keeping the depot fully functional throughout.

The Objective

Design and install a high-capacity dual EV charger with full civils and electrical works — ensuring safety, operational continuity, and future-proofed infrastructure for low-emission transport.

Challenges

Live Depot Operations

The MDU remained fully operational during the works. We had to maintain vehicle access, parking availability, and site safety throughout.
Integrated Design Approach

Our team needed to balance site limitations with load calculations and system performance, ensuring compliance and efficiency.

Our Solution

Design

Developed a tailored system to meet load requirements and integrate into the existing electrical infrastructure.
Civils

Constructed a new concrete base, installed trenching, and fitted key clamp guard rails for physical protection of the charger.
Electrical

Installed tray route works and SWA cabling to support the free-issued Kempower charger. Carried out all wiring, terminations, testing, and final commissioning.

Results

Sustainable Capability

The site now supports dual-vehicle EV charging, aligned with Network Rail’s carbon reduction goals.
Zero Downtime

All works were completed with no interruption to depot operations, preserving day-to-day functionality.
Compliance & Safety

Fully tested and commissioned to current standards, with all civils and electrical works integrated seamlessly into the site.
