Strictly speaking, the Sutton-in-Ashfield factory was on the GN line from Langwith to Annesley and Nottingham. The MR Pye Bridge line was diverted to join the ex- GN line just south of Kirkby, rejoining the ex-MR trackbed just north of Kirkby - immediately south of what is now Sutton Parkway station. The connection to the factory was retained, using a short stub of the GN line. Some of the rails for this connection still exist in places.
