Section 3 Sound

turned on to vent steam continually through the smoke box to create the necessary draft in a non-moving
engine. The blower sounds like a continual steam hissing sound.
4. Diesel and electric cab chatter:
These are the sounds of radio transmissions between the engineer,
dispatcher, switchman and hostlers. If you have ever been in a busy freight yard, cab chatter can often be
heard right from the open windows of idling engines. With QS-2+ you will hear real radio messages
recorded from actual train yards complete with radio squelch and beeps. Cab chatter occurs randomly.
RESET Position #25 allows you to turn off these sounds.
5. Diesel “Low Idle” in Neutral-Before-Reverse:
This special low idle sound occurs after the engine
has been in neutral before reverse for about 15 seconds and represents a special low idle condition for
diesels. This more soothing sound is included to allow the operator to place his engine on a siding or to
run different accessories without the distraction of the usual loud diesel motor sounds. If you want to
hear the loud diesel motor idle sounds in neutral, put the engine in Neutral-before-Forward.
6. Electric locomotive cooling fans:
The electric traction motors get hot and all electric locomotives
have cooling fans to help keep the temperature down. These powerful fans can create enough draft that
access panel doors cannot be opened. It is not surprising that these fans can easily be heard in idling
engines. The fan volume can be changed in RESET Position #6.
7. Steam “Pop-off” sounds:
If a steam engine builds up too much pressure in the boiler, special pop-
off values on the top of the engine will release the excess pressure in a fury of steam and sound until the
pressure is brought back to normal. This happens most often in neutral when the fire continues to build
up steam but the engine is not using any of this steam energy to do its normal work. This sound has
random lengths and comes on at random times.
8. Steam water injector:
Steam engines need to replenish the water in the boiler that is lost as steam
escapes through the smoke stack. Water injectors accelerate the water from the tender with steam
pressure to a high rate of speed to overcome the elevated pressure in the boiler. QS-2+ water injectors
sound like high speed rushing water and steam with a distinctive value shut off. This sound has random
lengths and comes on at random times.
9. Steam boiler Blow-down:
As water is evaporated into steam, mineral and other residues naturally in
the water are left behind to settle to the bottom of the boiler. When the accumulation becomes large
enough, the fireman will open a valve to vent this solid material through a large pipe under the side of
the cab directly to the ground. QS-2+ blow-down sounds like water, steam hiss and solid material
leaving a large pipe. This sound has random lengths and comes on at random times.
10. Horn in Neutral:
If the horn is set to operate in neutral (see RESET Position #25), the horn will
not interrupt any other neutral sounds.
11. Bell in Neutral:
Using the bell in neutral will not interrupt any of the other neutral sounds.
12. Coupler Sounds:
QS-2+ uses two sounds to model the coupler opening. The first is the sound of
the coupler pin chain being pulled taut as the coupler lift bar is being raised. This sound tells you the
coupler operation is armed. The second sound, which happens when the coupler is fired, is a
combination sound of the coupler pin being lifted, the knuckle opening and the air release of the brake
lines as they part.
