British Rail Class 31 (Brush Type 2) Locomotive
This loco use the same braking and multiple working logic as my previous locos and therefor can be worked in multiple with them.
How to Drive Loco:
- Press start Button in either cab or Local start in the engine room
- Activate the Master Key within the cab you wish to drive from
- Set brake to 0 and increase throttle as desired to control the speed of the loco
If the loco fails to start make sure the "Master" and "Engine Start" breaker is In and that the locos batteries have sufficient charge and that there is diesel fuel in the tank.
Cab controls not functioning, make sure engine is running and that no other Master control keys are active on the loco or other locos that have the multiple working cable (orange port) connected.
Braking system
The loco has a air operated brake system where the brakes on the loco are controlled by the pressure of air in the brake pipe. When the brake pressure is above 21; the brakes are released. Anything below that, the brakes are proportionally applied. The brakes system have two isolators to prevent the loco from both applying and or releasing the brake pipe (which can be used if loco are being worked in multiple) There is also a Manual brake release Key which will released the brakes disregarding the brake pipe pressure.
Power System
The engine speed is controlled by the air pressure in the regulating air reservoir which is controlled by the control desks. If the Amps of the main generator exceeds 2000 then the overload protection will trip and power will be lost. Power can be regained by returning the throttle lever back to 0 and then re-opening again. The overload protection feature can be turned off via the button on the control cubical in the engine room above the door.
Air System
Both the braking and power systems required air pressure to operate. The compressors with operate when the main air reservoir pressure drops below 35 psi and turn off when reaches 55 psi. If the main air res drops below 22 psi the general fault light will illuminate accompanied by a low air res warning on the control cubical; Power will be lost/won't establish and the brake will be applied. The low main air protection will return to normal once the main air pressure surpasses 28 psi.
