How do I drive steam train BC is -0.1 vac is 16.0 reverser is 75 forwards regulator is open at 30 both injectors are open and the cylinder cocks are open combo brakes also released.
If your vac is 16" the train brake is still applied enough to stop you moving. Everything else seems ok from what you've described make sure your small and large ejectors (note: not injectors) truly are open. You can close the large ejector again once the brake is at 21"+ and you're moving.
