Orient Way Traincare CET – Infrastructure Upgrade

Project Overview

The Orient Way Traincare Depot plays a critical role in maintaining Greater Anglia’s rolling stock, operating on a 24/7 basis. With aging and obsolete infrastructure, a major upgrade was required to modernise the CET system and associated depot facilities – while keeping the depot fully operational throughout construction.

Pod-Trak was appointed as Principal Contractor, leveraging our multi-disciplinary expertise to safely deliver the full civil, mechanical, and electrical upgrade scope within one of the region’s busiest live maintenance environments.

High Level Scope:

Safe isolation and removal of existing CET systems and redundant infrastructure
Installation of new mechanical and electrical containment routes (above and below ground)
Construction of new GRP access hop-ups and walkways, including strengthening and reconfiguration of driver access platforms
Installation of new CET network pipework, cabling, lighting columns, and illuminated bollards
Front-end cleaning system (Envirosump) installation
New sanding silo, facility building, and associated foundations, integrated with the silo system
Mechanical and electrical upgrades to pump houses and control systems
Depot signage, asset labelling, and car stop marker installation
As-built laser sweep structural gauging survey for clearance verification prior to entry into service

Key Challenges & Solution

Delivering extensive civil and M&E upgrades within a live operational depot required precision planning, strong coordination, and phased working.

All works were sequenced around depot maintenance schedules using pre-approved night and weekend possessions to ensure zero disruption to train servicing.
Pod-Trak’s team proactively identified and resolved GRIP 5 design gaps, closing out compliance challenges through collaborative workshops and constructability reviews.
Bespoke temporary works, segregated zones, and hop-up platform designs were implemented to maintain safe separation from operational tracks.
Early stakeholder engagement and resource levelling enabled the project to stay aligned with the CL32 Programme for Acceptance (PFA).

Innovation in Action

Pod-Trak applied a proactive and efficiency-focused approach by identifying AFC design issues early and resolving them through in-house engineering, preventing delays and reducing programme costs. Live depot works were delivered through digitally modelled phasing and access planning, enabling safe, optimised sequencing within a highly constrained environment. Productivity and quality were further improved by adopting precast and modular installation methods, which minimised manual handling, reduced on-site construction time, and enhanced safety and control. This approach was underpinned by rigorous clearance validation, ensuring all works were fully compliant and ready for energisation without risk of rework or delay.
