RDC, RAILBUS & DOODLEBUG SOUNDS
The automated type (9xx series) SOUND SYSTEM's
were designed for the model railroader utilizing
magnetic trips of the Horn and Bell. Each activation of
the Horn triggers a different prototypical play pattern of
the Horn. The Bell activates by a magnet tripping the
Bell on and then off.
This system can operate from track power and/or
battery power. It will automatically adjust the diesel
prime mover rpm with changes in track or motor voltage.
Sounds produced are appropriate for the type unit listed.
These systems can be mounted in the engine or car.
They can also be utilized in a stationary mode with the
Horn and Bell being triggered by either the train carrying
a magnet or other momentary switch input.
The sound systems are packaged with two reed
switches. Appropriate speakers can be found on page 6.
All of these sound systems have the same physical
appearance as the standard DCv3 sound systems seen
on page 14.
The standard DCv3 SOUND SYSTEM's were designed
for the model railroader utilizing a switch input or
LocoMatic™ controller for operation of the Horn and
Bell. They can be used with DC, DCC, Radio,
Stationary, and with AC track power (requires control via
the LocoMatic™ controller).
They are similar to the Diesel systems shown on page
10. They will automatically adjust the prime mover rpm
with changes in track or motor voltage.
Sounds produced are appropriate for the type of unit
listed. These systems can be mounted in the engine or
car (with track pickups). They can also be utilized in a
stationary mode.
Appropriate speakers can be found on page 4.
All of these sound systems have the same physical
appearance as the standard DC sound systems seen
on page 14.

While the Auto-Horn systems can be utilized with Radio
Receivers and Stationary use, we recommend using the
Standard DCv3 types that do not have the "auto-play"
feature. By utilizing a standard DC type system, the
Horn will only play as long as you keep the transmitter
function or switch input activated instead of playing
random Horn patterns when activated. This enables you
to play any pattern desired. For those that don't deem
this as important, or desire both reed switch and radio
receiver use alternately, then the "auto-play" units are
necessary.

The RDC New Haven units feature the Hancock Air
Whistle found on the New Haven RR. Standard RDC
units are equipped with a single chime horn as equipped
from the factory. Many railroads changed these horns
after delivery or use over a period of years.
