The Class 110 DMUs were built by the Birmingham Railway Carriage and Wagon Company in conjunction with the Drewry Car Co. to operate services on the former Lancashire and Yorkshire main line, and spent their entire careers based around this same area. This earned them the name of the 'Calder Valley' sets. They were an updated version of the Class 104, with a revised cab design and raised bodyside window frames.
