This Sunday (29 September) changes to services will be in place as TRU completes major upgrade work across two sections of the route from Huddersfield to Dewsbury and Leeds to York.
Sheet piling will be carried out at Mirfield station in advance of the new footbridge being installed, and to secure the track and ballast from movement during construction activities.
Before the new track is installed through the Mirfield area at a later date, engineers will also undertake formation work.
Sunday will also see the demolition of part of platform 3 at Mirfield station, whilst the extension of the platform eastwards will create space for the new footbridge.
In Ravensthorpe, the TRU team will complete mining mitigation work to probe, treat and infill voids within the old coal seams under the site, before further upgrades can be carried out in the area.
Elsewhere on the route, track renewal works will be carried out in Thorpe Park area between Cross Gates and Garforth, near Leeds.
Customers are encouraged to plan their journey ahead of time due to the impact these vital upgrades will have on services, with rail replacement buses and diversionary routes in operation.
