To the eastern side of the mainline, the Midland Railway had originally built a goods yard, which developed into a sizeable freight facility under British Railways, for collating and distributing goods around London. Resultantly, as the confines of the original depot with the introduction of electrification meant it could no longer be used, a new depot was built to the north east of the mainline, located directly north of the sidings and above the northern junction with the Dudding Hill Line.
