Northern Trains is preparing to launch a £300m construction framework covering infrastructure upgrades across its network of 22 train care depots and more than 470 stations.
The framework is scheduled to commence in March 2027 and will run for an initial five-year term, with the option to extend for a further three years until 2035.
It is intended to establish a long-term supply chain capable of delivering a broad range of works, including building refurbishments, depot fit-outs, major civil engineering, mechanical and electrical installations, track, electrification and signalling projects required to support existing operations and the introduction of new rolling stock.
The framework will be divided into four specialist lots covering internal building fit-outs, access and heavy component movement, integrated multi-disciplinary rail infrastructure projects, and specialist design-and-build servicing facilities.
The largest lot will cover a wide range of disciplines, including civil engineering, buildings, permanent way, electrification, high-voltage works, signalling, telecommunications, geotechnical engineering, drainage, highways, environmental improvements, and mechanical and electrical installations.
Northern said the framework would provide a flexible delivery model capable of handling projects of varying scale and complexity.
Contractors appointed to the framework will also be expected to promote continuous improvement, innovation and enhanced whole-life asset performance across the estate.
Ahead of the formal procurement, Northern has launched an early market engagement exercise, with a virtual supplier briefing planned for 14 July.
The operator is inviting feedback from the industry on the proposed framework structure, lot packaging, pricing models, commercial terms and risk allocation before issuing the official tender documentation.
