Maintenance Scenario - Horn Code is 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-
long
Horn code
to trigger the Maintenance Scenario. For maximum realism,
after
you enter the Maintenance
Scenario
15
, press (once only) the
Disconnect/Standby
key on your Quantum Engineer Controller
16
to put the
locomotive into the
Standby
17
state. Then use the throttle on your DC power pack to rev the
Prime Mover
up
and down without the locomotive moving. When you wish to end the Maintenance Scenario, press the
Start
Up
key on your Quantum Engineer Controller to return to normal operation.

Water Loading Scenario - Horn Code is long-short- short- short ( — · · · )
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
long-
short-short-short
Horn code
to trigger a Water Loading Scenario. For all locomotives, you will hear sounds of
water being run into the locomotive’s water tank. (Older diesel locomotives that supply steam heat to
passenger cars need to have their water supply refreshed periodically.)
3.11.2 Timing of Horn Blasts to Trigger Scenarios in DC Operation
It may take some practice to get the proper lengths of the
Horn
blasts so that they will trigger the three Scenarios
described above. The following information should help.
•
Minimum and Maximum Lengths (in msec) of Short Horn Blasts
A short Horn blast
is one of length greater than or equal to 0.2 second but less than 1.8 seconds. This is the
time you hold the Horn button down, not necessarily the length of time you hear the Horn sound play.
•
Minimum and Maximum Lengths (in msec) of Long Horn Blasts
A
long Horn blast
is one greater or equal to 1.8 seconds, but less than 10.0 seconds. This is the time you
hold the
Horn
button down, not necessarily the length of time you hear the Horn sound play.
•
Minimum and Maximum Separations in Time (in msec) between Different Horn Blasts
There is no minimum time. The maximum time between the end of one
Horn blast
and the start of the next
Horn blast
in a coded Horn sequence is 2.1 seconds.
Also, there must be 2.5 seconds of
Horn
off time before the start of another coded
Horn
sequence.
3.12 Additional Analog Operation Features Available with Quantum Engineer Controller
Your Atlas QSI sound-equipped diesel locomotive uses QSI’s QARC™ (Quantum Analog Remote Control)
Technology. QARC Technology uses special remote control signals to operate different Quantum features on a
conventional DC layout. With QARC Technology, you can operate features that are otherwise available only with
Digital Command Control (DCC). In particular, QARC will allow you to:
•
Turn on or off lights,
•
Shut down and start up locomotives,
•
Make up Consists easily,
•
Simplify Analog programming,
•
Set System Volume or Mute while train is operating,
•
Trigger Coupler Crash sounds,
•
Operate prototype-like Air Brakes,
•
Turn on Dynamic Brakes,
•
Activate verbal speedometer readout,
•
Operate many other features.
The QARC System makes Analog operation more fun and more prototypical. Every button on a QARC controller
does exactly what it is labeled to do. The major difference between QARC and DCC is that, with QARC, you are
15
These Scenarios cannot be started if the locomotive is in the
Standby
state (
Standby
is the 2
nd
phase of
Shut Down
). However, you can press
the
Disconnect/Standby
key any time after the Maintenance Scenario has started.
16
See Section 3.12 for information on the Quantum Engineer Controller.
17
See Section 4.1.14 for an explanation of the
Standby
state. The three Shut Down states (
Disconnec
t,
Standby
, and
Shut Down
) behave the
same way in both DC and DCC.
