The first batch of latter day redundant Bury Class 504 units were hauled from Bury to Warrington before going to MC Metals of Glasgow for scrapping in early 1991. After this point the reduced Bury–Crumpsall service was operated in four-car formation. In August 1991 the entire line was closed. The next day a Class 31 diesel hauled all the units from Bury to Warrington in two trains of units. From Warrington, the entire collection was towed to MC Metals in Glasgow.
