 In the mid-1950s as part of British Railways modernisation plan, projects were developed to centralise the marshalling of goods wagons and the associated servicing of steam locomotives at the United Kingdoms largest freight hubs.Teesside had a number of marshalling yards servicing the coal mines and steel mills of Consett, West County Durham and North Yorkshire, as well as those for Middlesbrough Dock.The decision was hence taken to rationalise these to one yard, Tees Marshalling Yard on part of the site of the once electrified Erimus Marshalling Yard.
