throttle’s movement from the initial setting (where Cruise Control was turned on). You can increase the laboring motor sounds in Cruise Control
as a train climbs a grade or decrease the Sound-of-Power effects as the train moves down the grade.
Return the throttle to its initial setting to avoid acceleration or deceleration when Cruise Control is toggled off.
Note:
Cruise Control is only available in Regulated Throttle Control or Speed Control. In Standard Throttle Control, F9 will produce in a Short Air Let-off.
Note:
Cruise Control is automatically turned off when the speed step is reduced to zero or track power is turned off.
Squealing Brake and Flange Sounds (F7)
Quantum provides automatic brake squeal as a locomotive slows to a stop. The operator can also control squealing sounds for
continuous and variable brake sounds for protracted stops or to simulate the sounds of squealing wheel flanges on curved track.
Squealing Brakes come on automatically when the speed is reduced from high-speed travel (over 35 smph) to less than 10 smph.
Pressing the F7 key when the locomotive is moving at any speed will manually activate Squealing Brake sounds, and repeated
pressings while the Squealing Brake sounds are occurring will continue the sounds uninterrupted.
Note:
If you slow the locomotive too quickly, the brake sounds will terminate abruptly when the locomotive stops and enters Neutral.
Note:
If you lower your throttle to speed step 0 on a moving locomotive, the F7 key will apply Air Brakes as long as the locomotive continues moving. See
next section.
Note:
The Gas Turbine does not have an Air Brake effect using the F7 key that is standard on later Quantum locomotives that actually reduces the speed
of the locomotive.
Dynamic Brakes (F5)
The prototype Gas Turbine locomotive has dynamic brakes that cause the train to slow down by using the traction motors in generator mode.
This helps dissipate the energy of a moving prototype train by converting it to electrical power, which is then applied to a large air-cooled
resistor load in the locomotive.
Pressing the F5 key in Forward or Reverse will set the locomotive Diesel Motor or Turbine sound to idle at the lowest Sound of Power
setting and turn on the powerful Dynamic Brake cooling fans.
Pressing the F5 key in Neutral and Disconnect (see Shut Down, next page), will turn on the Dynamic Brake Fans while Diesel Motor
sounds remain at idle.
The Dynamic Brake function automatically turns off when entering or leaving Neutral, or the speed of the locomotive drops below 7 smph
33
, or if
the throttle is turned up. The Dynamic Brakes cannot be turned on in Forward or Reverse unless the locomotive is traveling over 8 smph.
Note:
Dynamic Brakes do not increase the deceleration rate specified by CV 4 and CV 24.
Note:
Dynamic Brakes sounds will be barely audible over the Turbine roar in Turbine Mode.
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.

Note:
In Neutral, Mars is set at Dim to conform to general Rail Safety regulation Rule 17. In Forward and Reverse, Mars is pulsing.
Take Control of Automatic Cooling Fans with the F4 key to stop Automatic Control and select whether the Cooling Fans are on or off.
Take Control of the Pulsing Mars Light with the F12 key to change the Mars Light state progressively through states of Off, Dim,
Pulsing, etc. each time the F12 key is pressed.
Regardless of the state of the automatic fans (on or off), if you press the F4 key, the Cooling Fans will be set to on if the F4 key is “1” and off if
the F4 key is “0” and Automatic Control will be disabled. Thereafter, the fans will respond only to the state of the F4 function.
Note:
Automatic Control will be restored if the power is shut down and reapplied or if the F6 Start Up key is double pressed in Neutral (see the description of
Start Up at the bottom of this page).

Dynamic Brakes on prototype locomotives are less effective and are seldom used at low speeds.
