    Brief

    Northern Trains Limited seeks a supplier to design and install heavy maintenance infrastructure at Allerton Train Depot to support Class 331 fleet maintenance beginning March 1, 2028. The project focuses on enabling efficient bogie replacement operations on Road 4 and includes: installation of a synchronized vehicle jacking system capable of lifting up to 3 coupled Class 331 units; structural floor assessment, reinforcement, and leveling of pit areas; integration with the depot protection system to prevent unauthorized rail movements; design modifications to accommodate existing roof access equipment with adequate clearance during lifting; construction of concrete hardstands at shed ends to support forklift bogie handling; design and construction of segregated bogie storage (minimum 12 units, expandable to 16) and a covered charging station for battery forklift operations; swept path analysis and hazard identification for all material handling routes; and safety barrier installation between roads where required. All design, construction, environmental impact assessment, handover, and staff training must be completed before March 1, 2028. The solution must maintain depot operational functionality during construction, comply with railway and statutory standards, provide a safe working environment, and support the HM331 maintenance strategy while minimizing future maintenance requirements and allowing for operational flexibility.
