The raised railway is approximately 207 metres (680feet) long, a kidney shaped loop with access via a turntable from the steaming bays. Minimum radius of curvature is 10.5 metres. (35 feet). Ruling gradient is 1 in 100. It is suitable for 3 1/2" and 5" engines, which usually run anti-clockwise. There is currently no signal system, drivers are expected to drive at a sensible speed and be aware at all times of any other trains on the line. Coal & water are available at the station. All drivers on the track must be informed before the turntable is opened.
The plan below shows more detail of the site and other technical data.
Both railways are super elevated for 6 mph in the curves - (4 mph in the GL Loop) and all curves have leading and trailing transitions.
The ground level railway is also aproximately 207 metres (680 feet) in length on the main line, 214 metres via the loop (702 feet)
Minimum radius of curvature is 14 metres (46 feet). Ruling gradient is 1 in 100 . There is a loop at one end for trains to pull into a station area. It is suitable for 5" and 7 1/4" engines which run clockwise. Entry to the station loop is controlled by a card reader to change the points. Drivers will be issued with a card, but this must be returned when running is complete.
The card reader is the small wooden post to the bottom left of the picture. The signals are set with the feather lit to go through the points left to the station loop.
Both the main line and station loop have signals to protect trains when cars are crossing.
Signals control trains from the station area rejoining the main line.
A TSMEE member will be 'on duty' in the station area and will alter points to allow access back onto the main line when it is safe to do so. Coal and water are available in the station area only, as visibility is limited when passing the steaming bay area.
The station loop on the left rejoining the main line on the right of the picture with a shunt ahead.
The steaming bay area is raised to allow easier access to steam up etc. A 1 in 50 gradient brings engines down to ground level. A TSMEE member will ensure other users are aware that another engine is to join the main line, then will operate the points at a safe time to allow access. The points will then be returned immediately to the main line position.

In order to safely unload engines from vehicles or trailers, we have installed a traverser. The picture below shows the load test to 16cwt! The safe working load will be 7cwt. The traverser moves side to side & is raised with a 4 ton hydraulic ram.
The traverser is situated close to the steaming bays inside the ground level loop. Access must therefore be managed by a TSMEE member as the vehicle must be reversed across the track, where engines may be running.
Points & Signals. the plan below shows the position of the signals.
Signals S1,2 and 3 are automatically controlled by the setting of the relevant points.
Signals S4 and 5 are controlled by the station master, and are there to halt trains when vehicles are crossing the track to the steaming bays.
Signal S1 is 3 aspect, with a white feather to indicate the route through the points.
Between signals S1 and S5 the track is worked as a block (due to the limited visibility round the curve). S1 shows red until the previous train has cleared the block.
A red light will also be displayed if the points are jammed in the mid position.
A yellow light will be displayed if signals S4 or 5 are at red.
S5 will only show green if the points from the steaming bays (P4) and the points from the station platform (P3) are set for the main line.
S2 will only show green if the points (P2 and P3) are set to return to the main line. This signal also carries a ground signal which, when clear, allows access to the head shunt when the main signal is red.
Points P1 are changed by the station master, therefore anyone needing to come into the station loop needs to inform the station master on the previous circuit.
