F4 Brake On pressing F4 the sound of the brakes being applied will be heard. At the same time, if the throttle is set to zero, the loco will slow down as if the brakes have been applied. The rate of braking can be adjusted via CV4. As per the prototype, the engine will be heard to notch into fast idle whilst the brake is ON.
