Advanced Analog Features
Starting the Locomotive
Most HO DC power packs with a standard reversing switch
2
are suitable for Analog operation. Generally, modern electronic type power packs
will provide better performance.
When operated with a standard DC power pack, your Quantum equipped Gas Turbine locomotive behaves quite differently from other
locomotives you may have operated. Unlike standard HO locomotives that start at very low track voltages, Quantum equipped locomotives
require a minimum amount of voltage to operate the electronics.
Turn the throttle up slowly. The Number Board Lights will turn on first
3
. As the voltage is increased further, you will hear the Quantum
System™ come on with a Long Air Let-off sound. The Mars Light will turn on steady and the Headlight will be off (See a table
summary of Directional Lighting Operation in the DCC section of this manual). If you are in Diesel Mode, you will hear the motor in the
diesel locomotive start up followed immediately by the Air Pumps.
Continue
4
to turn up the throttle voltage until the locomotive starts to move in Forward (this voltage is called V-Start
5
). The Headlight
will switch on bright and the optional Mars Light will begin to strobe.
As you slow the locomotive down by gradually reducing the throttle to a little below V-start, the locomotive speed decreases, while
Squealing Brake sounds occur as the locomotive comes to a slow stop
6
.
Note:
If you need to turn your throttle up quite high to start your Gas Turbine locomotive, V-Start can be adjusted for operation with your particular DC
power pack (see Analog Programming on pages 9-11). For recommended power packs, consult the
Quantum Analog Reference Manual

Doppler Effect
This sound effect changes the pitch and volume of the Horn, Bell and other diesel sounds as the locomotive passes by.
While the locomotive is moving toward the observer, flip the direction switch to turn on the Horn.
Wait at least one second while the Horn is blowing.
Just before the locomotive passes in front of the observer, flip the direction switch back and forth quickly so the Horn does not shut
off. You will hear the Doppler Effect as the locomotive passes by.
Either flip the direction switch back to shut off the Horn, or continue with long or short Horn operations. When you are finished blowing
the Horn, the locomotive sounds will automatically return to normal after a few seconds. If the Bell was on, it will shut off just before
the sounds return to normal.
Note:
The faster the locomotive is moving, the greater the Doppler shift. Below 15 smph, there is no Doppler shift.
Neutral
In Neutral, the Gas Turbine will continue to make prototypical sounds appropriate to its resting state.
Enter Neutral by
turning the throttle down below V-Start but not off and wait for locomotive to stop
7
. The Headlight or Mars
Light switches to a steady dim. The and Reverse Light will remain on if entering Neutral From Reverse (NFR).
You will hear a Short Air Let-off when the locomotive stops moving and enters Neutral, and a Long Air Let-off about three seconds
later followed by Air Pumps and other background sounds. In addition to the pumps, diesel motor Cooling Fans and Vents will come
on at random time intervals in Neutral. After ten seconds the diesel motor Cooling Fans shut off if they were on when you entered
Neutral.
If the Gas Turbine locomotive is in Diesel Mode and left in Neutral From Reverse, a special Low Idle state marked by subdued
throbbing motor sounds will automatically come on after 30 seconds (see description of Low Idle in the section on Quantum System
Sounds on page 24). The Gas Turbine locomotive will return to normal Diesel Motor sounds when the throttle is turned up.

Some electronic power packs do not have a reverse switch. Instead they have a reverse button, which does not cause a rapid change in track polarity to the track
and is not suitable for Quantum operation. See the list of suitable power packs in the
Quantum Analog Reference Manual
(Version 3) at http://www.qsindustries.com.
3
Number Board Lights for the Gas Turbine are directly wired to the track power and will be on whenever track power is applied.
4
It is not necessary to wait for the engine Start Up to finish before entering Forward. If you turn up the throttle, the Start Up sounds terminate and the locomotive will
immediately go into normal Forward operation.
5
V-Start is set at 8.5 volts. It is important to note where V-Start is located on your throttle control to know where you will enter and leave Neutral (see
Neutral
on Page
4).
6
Squealing Brakes occur if the locomotive exceeds 40 scale-mph (smph) and then slows down to below 20 smph.
7
If Regulated Throttle Control is enabled (see below) it is important to wait until the locomotive stops on its own. The locomotive’s electronic inertia will keep it moving
even though you have reduced the throttle far enough below V-Start to stop the locomotive. In your attempt to stop the locomotive, do not try to reduce the throttle so far that all
sounds go off.
