Overview

Northern Trains Limited, is a Train Operating Company (TOC) that operates passenger rail services across the North. Northern Trains Limited is publishing this notice to establish a contract with a single supplier for the construction of full-length high-level access platforms based on designs from RCA Construction, enabling safe working at height along the entire length of four-car trains.

These platforms will be compatible with existing fleets (Classes 323, 768, and 331) as well as any future fleets operating at Allerton depot. They will be installed on one road to improve operational flow, particularly in the Planned Heavy Clean (PHC) area.

The platforms will incorporate essential safety features, including barriers, fall protection systems, and appropriate signage to ensure safe use by staff. A key functional requirement is the inclusion of a safe method for removing roof-mounted components, such as HVAC units, while minimising manual handling risks.

Regulations cited

  • Railways Act 1993

Additional details

In addition, the high-level access platforms must integrate with existing overhead line equipment (OHLE) isolation systems and the depot protection system. This ensures that the platforms cannot be used unless the overhead electrical supply has been fully isolated, thereby maintaining a high level of safety for maintenance activities.

The nature of the arrangement is that works will be supplied under a JCT intermediate Works with Contractors design 2024.
