These STEAM LOCOMOTIVE SOUND SYSTEM's were designed for the model railroader utilizing magnetic trips of the Whistle and Bell. Each activation of the Whistle switch triggers a different prototypical play pattern of the Steam Locomotive's Whistle. The Bell activates first by tripping the Bell sound on. The second trip will signal the Bell to turn off. Whistle triggers can occur during Bell triggers as well. This system can operate from track power and/or battery power. The steam locomotive sound system will automatically adjust the chuff rate with changes in track or motor voltage. It can also be synchronized with optional switch inputs or utilizing our optical input. Sounds produced are similar to the standard DC sound systems (Dallee Catalog, page 7) except the Whistle and Bell are triggered on and off with various Whistle play patterns. The sound systems can be mounted in an engine or car (with track pickups) or they can be utilized in a stationary mode with the Whistle and Bell being triggered by either the train carrying a magnet or other momentary switch input. These systems are packaged with two reed switches. To make life easier, we made available the more pleasant and popular steam whistles. All 9xx series sound systems have the automatic Whistle / Horn play patterns. Steam sound systems available are listed below as well as our price schedule. They have the same physical appearance as the standard DC sound systems shown previously.
