Most of the locomotives stabled at Mexborough were used for hauling coal trains. The coal originated from the many collieries in the South Yorkshire coalfield and wagons of coal were despatched to locations all over the country. However, the main destinations were the industries and power stations in Lancashire. With the opening of the Wath marshalling yard in 1907, Mexborough supplied locomotives for collecting wagons from the collieries, for re-marshalling of the wagons at Wath and for hauling coal trains across the steeply-graded "Woodhead" route across the Pennines into Lancashire. In the 1920s, the depot was the stabling point for what was then the most powerful locomotive in the UK, the London & North Eastern Railway's Class U1Garratt. It was used for banking heavy coal trains up the Worsborough incline on the Woodhead route.[2]
In 1942 during the Second World War, three former Great Eastern Railway LNER J15 locomotives were drafted-in to assist with coal traffic.[3]
In the 1950s, the route from Wath to Manchester was electrified. Consequently, the demand for the steam locomotives from the Mexborough depot reduced. The electric locomotives were stabled at Wath rather than Mexborough. Even the steam shunting engines for the marshalling work at Wath yard were replaced by diesel shunters in 1957.[4] The use of steam locomotives for collecting coal from local collieries was also phased out and the depot closed in 1964. The site of Mexborough depot is now occupied by units in an industrial estate off of Meadow Way in Swinton.
In its heyday, the depot had its own football team, Mexborough Locomotive Works F.C.
