RS-3 ALCO 244-12
The ALCO RS-3 is a 1,600 hp (1.2 MW), B-B road switcher diesel-electric locomotive. It was manufactured by American Locomotive Company (ALCO) and Montreal Locomotive Works (MLW) from May 1950 to August 1956, and 1,418 were produced — 1,265 for American railroads, 98 for Canadian railroads, 48 for Brazilian and 7 for Mexican railroads. It has a single, 12 cylinder, model 244 engine.
CV155 Notching mode should(must) be =1: 0 = Auto, 1 = Semi auto, 2 = Manual 
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 F11 and F7, if you want your engine to sound
like it is working harder. Manual mode offers full control of the notch setting using F11 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 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
This sound project has been assembled from Digitrax-supplied sound clips as well as new sounds from custom recordings.
Please see project description for full description and list of features.
With Digitrax Sound FX decoders and downloadable sound project files (.spj), you can download your choice of sound schemes into any Sound FX equipped locomotive. You can use spj’s that are available for free, you can modify those schemes or you can create your own!
Digitrax offers a wide variety of Sound FX decoders to fit many different locomotives. You’ll need to have a Digitrax SFX decoder installed to take advantage of using .spj files.Click here for Digitrax Sound FX decoders
