The joint station did not acquire the "High Level" and "Low Level" names until 1924. Since it was expected that only local trains would call, the platforms were on loops, with the running lines left clear for expresses. At that time there was a north to west curve linking the, by then, Midland with the LNWR line. Since it was the crossing of two major lines – one Bristol to Newcastle, the other Euston to Aberdeen – it was important for the Royal Mail transferring upwards of 2,000 bags every night.
