As part of Phase 1 of the Kent Coast Electrification Scheme, the yard at Hoo Junction had a simple overhead catenary system installed in 1959, to accommodate the Class 71 electric locomotives then brought into use.
These were equipped with a pantograph to work off the catenary, intended to avoid the exposed third rail which could have added a danger for yard staff.
Westinghouse Rail Systems has buildings adjacent to the north perimeter of the yard.
The majority of traffic is aggregate wagons, with steel strip carriers are also present.
Hoo Junction Staff Halt opened in 1956 in the yard, which it was built to serve.
