The current depot was designed in the 1960s to service electric locomotive classes AL1 to AL6 (TOPS classes
81,
82,
83,
84,
85 and
86); subsequently, in the early 1970s, Class
87s were included. It consists of six parallel shed roads, each holding four locomotives inside the shed, and several arrivals and departure sidings externally. There is also a road that runs round to the north of the shed, which provides access to the fuel siding; for many years, this was used only for the occasional fuelling of diesel shunters and also to the DC lines of Willesden Junction Low Level station, which is used to move multiple units from the shed onto the North London Line after servicing. The arrival and departure sidings contain two connections to the West Coast Main Line onto the up slow line. At the east end of the depot, there is a trailing crossover to permit access onto the down slow line when coming off depot. ==Facilities==
