An interesting survivor just north of Pontefract is the Prince

of Wales Colliery signal box. Constructed by the Lancashire and Yorkshire Railway in 1912 it controlled the level crossing and entry/exit into the big colliery of the same name. The lines that went into the mine complex can still be seen to the left of the picture. This drift coal mine finally closed in 2002 and the site is now occupied by an extensive housing estate that was still under construction at the time of our visit.
