3.8 Sound of Power™
Your QSI-equipped diesel locomotive will produce
Sound-of-Power
labored Prime Mover sound effects if you have
selected any of the Load Level settings from 1 to 15. Under acceleration, the engine sounds will be more labored until
the locomotive has achieved its final speed, at which point it will then produce standard sounds appropriate to its
throttle setting. Under deceleration, the
Prime Mover
sounds are less labored until the locomotive achieves its final
speed, where it will again produce standard
Prime Mover
sounds appropriate to its throttle setting.
3.9 Helpers
Prototype
Helpers
are locomotives that are used to provide extra power and/or braking for a heavily loaded train.
These locomotives can be part of the head end
Consist
, act as mid-train
Helpers
, or serve as
Pushers
at the end of
the train. Helper locomotives behave differently from the train’s
Lead Locomotive
. The Horns and Bells on Helper
Locomotives are usually not operated, and their lighting options are different or not used at all.
When you make up your train using more than one locomotive, the QSI sound-decoder (Quantum™, Quantum
Titan™, or Quantum Titan™ with ET). allows you to program easily how each locomotive will behave by selecting
between a
Lead Locomotive
,
Mid Helper
,
End Helper
, or
Pusher
. Each type of Helper Locomotive has different
lighting and sound characteristics, as described in Table 1 of Section 3.13
Analog Programming
.
3.10 Normal and Reversed Direction
A QSI sound-decoder (Quantum, Quantum Titan, or Quantum Titan with ET). allows you to reverse the directional
sense of your locomotive in DC operation. This is normally not an issue with DC two-rail trains since all locomotives
will go in the same direction whether they are facing forwards or backwards. However, certain features like directional
lighting do depend on the directional sense. For instance, if you program your locomotive to be an
End Helper
, its
Rear Headlight
operates when the locomotive is moving in
Reverse
, and the
Front Headlight
is disabled. This is ideal
for providing a
Rear Headlight
for the train. Normally, if this diesel locomotive is facing backwards at the end of a
Consist, its
Rear Headlight
will be facing forwards and will be lit when the Consist is moving forward; furthermore,
there will be no Rear Headlight for the Consist. The
Direction
programming feature will ensure that this End Helper’s
backward-facing
Front Headlight
will come on
only
when the Consist is backing up, and the forward-facing
Rear
Headlight
will not light at all. When making up a train with different Helper types, it is recommended that you also
change the directional sense of any Helper that is intended to be operated backwards within the Consist. See “Option
4
, Direction
” in Table 1, Section 3.13.
3.11 Fuel Loading, Water Loading, and Maintenance Scenarios (firmware Versions 8 & 9
only)
HO scale and 2-rail O scale Atlas Gold Series locomotives that are equipped with a QSI sound-decoder using either
Version 8 or Version 9 firmware (i.e., Quantum Titan or Quantum Titan with ET) include three different scenarios that
cover the following situations:
•
Loading fuel into the locomotive,
•
Performing maintenance on the locomotive,
•
Loading water into the locomotive.
3.11.1 Triggering the Scenarios in DC Operation
The three different scenarios are available in both conventional DC operation and DCC operation. With DC track
power, these Scenarios are triggered by sequences of long and short blasts of the
Horn
. The locomotive must be in a
Neutral state, either
NFF (Neutral from Forward)
or
NFR (Neutral from Reverse)
before you can trigger any of these
scenarios.
•
Fuel Loading Scenario - Horn Code is short-short-long ( · · — )
When the locomotive is in the
NFF (Neutral from Forward)
or the
NFR (Neutral from Reverse)
state, use
either the
Horn
button on the Quantum Engineer or the direction switch on your power pack to blow a
short-
short-long Horn code
to trigger the Fuel Loading Scenario. For diesel locomotives, you will hear sounds of
diesel fuel being pumped into the locomotive’s fuel tank.
