Each of these railway companies went through various takeovers and amalgamations, until the early 20th century, when the station at Barnsley was co-owned by the Lancashire and Yorkshire Railway (LYR, successor to the M&LR), and the Great Central Railway (GCR, successor to the MS&LR and SYD&G). At the 1923 grouping, the GCR became part of the London and North Eastern Railway (LNER), whilst the LYR formed part of the new London, Midland and Scottish Railway (LMS), as did the Midland Railway (MR). The LYR and MR each contributed one station in Barnsley to the LMS, and since the ex-MR station was already distinguished as , the LMS renamed the former LYR station to "Barnsley Low Town" on 2 June 1924. Just two months later, on 1 August 1924, it was again renamed, this time to "Barnsley Exchange".
