The fort was linked to a jetty, Coalhouse Wharf, on the riverside a short distance to the south.
A standard gauge railway track led from the fort's interior to the jetty and was used to bring guns and supplies from the wharf.
The heaviest guns were transported to and from Coalhouse Fort (and other Thames forts) aboard two specialised gun barges called Gog and Magog, built in 1886 and 1900 respectively and used until the 1960s.
The remains of the jetty are still visible, as are sections of the track within the fort's entrance.

A two-storey concrete structure just north of the fort was used during the Second World War as an Extended Defence Officer's Post to control the minefield outside the fort.
It could also serve as a pillbox.
A corresponding post stood on the Kent shore.
A small concrete structure a further 148 feet (45 m) north-east of the fort may have been an electrical power house.
The minefield was overlooked by a hexagonal radar tower about 1,300 feet (400 m) south of the fort, consisting of a concrete structure on a metal frame on which the radar array was mounted.
This stands atop a brick building in which the power plant, electrical equipment radar screen and personnel accommodation were located.
It was only used for a short time between 1941 and 1943 and is now considered structurally unsafe.
Situated nearby is the detached battery built in 1893 to mount four 6-pdr.
quick-firing guns.
It is well-preserved and the emplacements, ready-use lockers and magazines are all still largely intact.
