Squealing Brake sounds and the final distinctive squealing sounds as the
Quantum equipped steam locomotive slows to a stop.
Dynamic Brakes:
Steam locomotives do not have Dynamic Brakes. When
steam engines are operated today, they are often coupled to a diesel to
provide dynamic brakes on down grades. If a Quantum steam engine is
coupled to a Quantum diesel, and Dynamic Brakes are activated, the diesel
Dynamic Brake effect will start up and the steam engine labored chuffing
will reduce at the same time. Since prototype dynamic brakes are relatively
ineffective a low speeds, the Dynamic Brakes will shut off automatically
below 8 smph and steam engine Chuff will return to normal.

QARC Only.
Whistle:
The Quantum System uses authentic locomotive sounds
whenever possible. All Quantum Whistles are engineered by our sound
experts to give you the most authentic effects. If you blow the Whistle
briefly, you will produce a realistic short Whistle sound or “hoot”. Some
locomotive models have special Whistle Endings to allow the whistle to be
“played” when desired.
Bell:
Steam engines can have either a pull bell or pneumatically operated
mechanical bell. With pull bells you will hear a different sound as the bell
swings forward and backward producing the familiar ding-dong effect.
Pneumatic bells produce a very repetitive ring and often much faster ring
rate than a pull bell. During turn-on in Neutral, hear the pneumatic clapper
gain greater throw with each stroke until it finally sticks the Bell. During shut
down in Neutral, you will hear the Bell sound fade out for either pneumatic
or pull Bells.
Doppler Run-by:
The engine sounds get louder as the train approaches,
then immediately drop to a much lower pitch and lower volume as the train
passes by. With a little practice you can change the pitch exactly when and
where you want. Doppler shift is based on the speed of the engine, so the
sounds change more dramatically when the engine is running faster. After
the Doppler shift has occurred and the Whistle is no longer being blown, the
Bell shuts off automatically and locomotive sounds return to normal.
Coupler:
To give you the most authentic coupler sounds, we have identified
three distinct types of coupler activity. The first is when the coupler is Armed
where you will hear the clanking sound of the coupler lift bar and coupler
pin raising. The next is Firing the coupler, where you hear the opening
of the coupler with the hiss of the air-lines parting. The third is when the
locomotive couples up to its load of cars, and you hear the Coupler Crash
