 The original authorisation had included a curve to the Midland Railway (former North Midland Railway section) Rotherham to Leeds line; it was a short curve from Sandal junction to Walton junction.This had not been submitted for inspection earlier, and Captain Tyler looked at it on 5 June 1866, but he declined to sanction opening of it at first.He later agreed to the use of the curve on 31 July, and it was opened on 1 September 1866.
