Overview

​​

Glasgow Central Station is the busiest station in Scotland and the fourth busiest in the UK. Within the station’s Signalling Centre, asbestos fibres were identified in the power and compressor room, resulting in severe access restrictions and the inability to safely maintain critical operational assets.

​

These assets support some of Scotland’s Railway’s most safety-critical E&P, Signalling, and Telecoms systems. Without intervention, the restricted access posed a growing risk to the safe and reliable operation of train services in and out of Glasgow Central.

​

To remove this risk and ensure long-term operational resilience, Network Rail commissioned the delivery of a new, fully segregated Principal Supply Point (PSP).

​

​

The Challenge

• Asbestos preventing safe access for maintenance activities

• Ageing infrastructure supporting critical operational systems

• Delivery required within a live operational railway environment

• Zero tolerance for disruption at Scotland’s busiest station

• Complex interfaces between power, signalling, telecoms, and compressed air systems.

The project demanded meticulous planning, robust engineering solutions, and close collaboration across multiple disciplines.

​

​

Our Solution

We were appointed to design, construct, and commission a new segregated Principal Supply Point, removing reliance on the restricted building while maintaining continuous railway operations throughout the programme.

The solution was developed to:

• Eliminate asbestos-related operational risk

• Improve resilience and long-term maintainability

• Provide compliant, future-proofed infrastructure

• Deliver with no impact on passengers or train services

​

​

Scope of Works

• One new Principal Supply Point distributed across three buildings

• Foundations, hardstandings, compounds, and access roads

• New Distribution Network Operator (DNO) power supplies

• Four new 100 psi compressors with associated driers and control equipment

• Compressor systems split across two buildings to enhance resilience

• New power supplies for Signalling and Telecoms systems

• Compound lighting

All works were fully designed, built, tested, and commissioned as part of a single integrated delivery.

​

​​

Results

• 15 months from initial engagement to operational handover

• Zero incidents

• Zero train delays

• No impact on the operational railway

• Removal of asbestos-related maintenance risk

• Enhanced resilience of critical power and compressed air systems

The completed infrastructure now provides a robust, maintainable solution supporting the long-term reliability of Glasgow Central Station.
