In February 2019, it was revealed that Mirfield was in line for a new station as part of the £3 billion TransPennine Route Upgrade. The plans involve the reconstruction of the current platforms 1 and 2 on what will become the 'slow' lines between Heaton Lodge and Thornhill LNW junctions, along with the restoration of the fourth line to complete the 'fast' lines between those two points. The existing platform 3 would be demolished under this scheme.
