Introduction
A new GBP 46.5 million maintenance depot has opened in Huddersfield, as part of the Transpennine Route Upgrade (TRU) project. The facility, known as Hillhouse Light Maintenance Depot, will support Northern’s fleet operations, including maintenance, repairs, and cleaning to ensure reliable train services across the North of England.
Hillhouse Light Maintenance Depot
The Hillhouse Light Maintenance Depot, formerly known as Hillhouse Sidings, has been transformed into a state-of-the-art facility. The depot operates 24 hours a day and includes five maintenance lines capable of accommodating up to 24 carriages. Initially, engineers will focus on diesel trains on two of the lines, with the remaining three lines scheduled to open in the coming years to support electric and bi-mode trains within the TRU programme.
Transpennine Route Upgrade (TRU)
The Transpennine Route Upgrade is a multi-billion-pound investment project. The project covers a 76-mile railway between Manchester, Huddersfield, Leeds, and York. The TRU aims to enhance services by providing faster, more frequent, and reliable services, increasing capacity, and reducing carbon emissions through electrification.
Huddersfield Station Redevelopment
Huddersfield station is also undergoing major redevelopment as part of the wider works. Three platforms have been reopened after extensive rebuilding and extension. The next phase of construction will continue until early 2027, focusing on completing the final platform, canopy, and track improvements. Upon completion, the station will be able to accommodate longer trains with increased capacity and improved passenger comfort.

This depot will not only support more reliable services today, but it’s also future-proofed for electric and bi-mode trains, making it a key part of building a greener, faster and more dependable railway for years to come.”
