 In 1879 when the Swinton and Knottingley Joint Railway was opened, double connections were laid in with the WR&GR.These ran from the east side of the S&KJR into South Elmsall station, and from the west side of the S&KJR, at Moorthorpe station, to the south side of the WR&GR at Moorthorpe junction; the latter connection was used by the Sheffield-Leeds service of the MS&LR.In October 1880 the converging junction from the Adwick line at Haggs Wood junction was shifted to a new connection at Stainforth station, and Haggs Wood signalbox was abolished.
