This is the RAM 51 HO Gauge Steam Engine Sound Sound System by RAM Track.

This device provides chuff and hiss sound that is electronically triggered by the turn of the axle for proper cadence with the engine's drive wheels.
The entire system is small enough to fit in some tenders or in a car directly behind the engine.
The digitally accurate sounds come from an amplified, 1-3/16" x 3/4" circuit board prewired to a 1" speaker.
Once adjusted it will not go out of cadence when cars are added or removed from the train.
Made in the USA.
