RDC Detroit Diesel 6-110
The Budd Rail Diesel Car, RDC or Buddliner is a self-propelled diesel multiple unit railcar. In the period 1949–62, 398 RDCs were built by the Budd Company of Philadelphia, Pennsylvania, United States. The cars were primarily adopted for passenger service in rural areas with low traffic density or in short-haul commuter service, and were less expensive to operate in this context than a traditional locomotive-drawn train. The cars could be used singly or several coupled together in train sets and controlled from the cab of the front unit. The RDC was one of the few DMU (diesel multiple unit) trains to achieve commercial success in North America.
The war years saw improvements in the lightweight Detroit Diesel engines and, just as importantly, the hydraulic torque converter. Budd, which by then had produced more than 2,500 streamlined cars for various railroads, took a coach design and added a pair of 275 hp (205 kW) 6-cylinder Detroit Diesel Series 110 engines. Each drove an axle through a hydraulic torque converter derived from the M46 Patton tank. Budd broke with the "railbus" designs of the 1920s–1930s and used a standard 85-foot (26 m) passenger car shell. The cars could operate singly, or in multiple.

=================================
(C) General Notes
This is a functional tested version of a project using individual sound recordings for each prime mover notch setting. These
prime mover sounds can be played in three modes determined by CV155: automatic, semi-automatic and manual notching. In auto
mode, the prime mover notch is determined by the current speed setting, and is adjustable using CV132. In semi-auto mode,
the same is true but it is possible to "throttle up" to higher notches using F6 and F7, if you want your engine to sound
like it is working harder. Manual mode offers full control of the notch setting using F6 and F7, so you can throttle down
to idle and turn on dynamic braking while coasting downgrade.
Other features available in this project include:
- Automatic grade crossing horn sequence with bell
- Optional highball and backup horn signals while stopped
- Dynamic brakes at speed or standing
- handbrake while stopped
- Automatic coupler sounds when changing direction at low speeds
- Automatic brake squeal sounds when decelerating to a stop
- Manual brake squeal on F9 and moving
- Additional user-defined sounds on F14 and F15
This sound project has been assembled from Digitrax-supplied sound clips as well as new sounds from custom recordings.
Additional custom 16bit 44KHz files were used to edit individual sound fragments (WAV files for each file handle).
It will be a copyrighted project on acceptance by Digitrax.
Thanks are due to A.J. Ireland for their prior work in developing sound projects.
For CV155=01 ["Semi_automatic Notching"], the Prime mover lowest Notch setting is set by
the throttle speed setting. F6 (ON) can increase the Notch and F7 (ON) will decrease the
Prime mover to the minimum notch set by current throttle setting.
The sound volume is controlled by Master Volume CV58 as well as any individual sound
volume CVs. The Default for CV58 is 5 but can be set 0-15 from a Throttle or the sim-
ulated throttle in SoundLoader. Individual sound volume CVs can be set 0-64.
