key will apply Air Brakes as long as the locomotive continues moving.
See next section.
Air Brakes (F7)
If you have selected any non-zero deceleration inertia or momentum value
in CV 4 and/or CV 24, the F7 key can be used to apply Air Brakes to stop
the engine more quickly than it would normally stop from the inertia settings
28
. To use Air Brakes:
•
Turn the throttle down to speed step 0 on a moving engine; this
enables the F7 key to act as a brake.
•
Press the F7 key. Hear a brief brake squeal sound and air being
released from the brake lines continually. The longer the air is
released the greater the braking action.
•
Press the F7 key again to stop the air release. The train will continue
to slow at the last braking value.
•
If you want to apply more braking, press the F7 key again to release
more air. When you reach the desired amount of braking, press F7
again to stop the air release.
•
Turn up the throttle to any value above 0 to release the brakes; this
returns the engine’s deceleration to a value determined by the sum of
CV 4 and CV 24.
•
If the engine is in Neutral when the F7 key is pressed, a long air
release sound simulates setting the brakes. However, no braking
effect is activated
29
.
If the throttle is set to any speed step except 0, Air Brakes are not enabled;
instead the F7 key will now manually activate Squealing Brake/Flange
sounds but will not affect the engine’s deceleration.
Automatic Features with “Take Control” Operation
The Quantum System allows the operator to take control of certain
automatic features by using their associated function key. Once you “Take
Control”, the features will no longer have automatic operation and you will
control their operation and their state with their function key commands.
Automatic and Take Control operations are described in the table below.
