Network Rail plans to radically increase capacity at a bottleneck on a key rail route across the North of England. It is not the notorious Castlefield Corridor in Manchester – yet. The troublesome section in question lies to the east, between the towns of Huddersfield and Dewsbury, where a two-track section would be quadrupled. The works would significantly increase capacity for both freight and passenger services connecting ports and installations on both the east and west coasts of the UK.
