The Sheffield district rail rationalisation plan of the 1960s called for the replacement of the majority of the marshalling yards in the Sheffield area with one large yard. A location on the Sheffield District line was chosen and work started in 1963 with new connections being built at Treeton, Broughton Lane and Tinsley South. The 80 yard Tinsley Wood Tunnel and approach cuttings were filled with some of the material excavated from the new yard, the remaining material being transported to a tip at Orgreave. The location allowed easy access to the brand new central Sheffield Freight Terminal at Grimesthorpe, and the new Freightliner terminal on the site of the Masborough Sorting Sidings in Rotherham, one of the many yards that Tinsley replaced.
