The Raised Level Track is of 2½, 3½ and 5 inch gauges. It is built from rolled flat steel bar of ¼ x 2 inches mounted on resilient blocks of either wood or high density polyethylene on concrete posts, the rail level being about 20 inches above the ground.
The layout is in the shape of a dumbbell and the direction of running is clockwise. Three-aspect colour light signals allow the passage of four separate trains at safe intervals.
The length of the circuit is 349 yards. Minimum radius is 39 feet and the maximum adverse gradient is 1 in 100.
The width of any train or part of it should not project more than 3 feet from the rail centre line. There are no restrictions on height at present.
There is a covered steaming bay area with road access. A manually operated traverser, with deck 20 inches above the ground, allows transfer from road vehicles to the steaming bays and to the running track. There are eight steaming bays but no power supply for steam-raising blowers.
The riding cars are stored in the carriage shed alongside the station. There are six riding cars with two bogies and hand-powered brakes. For lightweight locomotives, there is also one six-wheel riding car with hand-operated brakes. Riding cars brought by drivers of visiting locomotives will need to come fitted with a magnet to operate the signals.
Facilities for coal and water
Coal is available in the bunkers beside the running shed. Water is available at the running shed and at the station (Dobson’s Halt).
Loading and unloading passengers
All trains should pick up and deposit their passengers at the station and not at the steaming bays.
