This is the same system electronically as the HO
unit but has a 2" speaker which creates greater volume and can fit easily into
most O or G gauge tenders and cars.
This on board 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. Once adjusted it will not go out of
cadence when cars are added or removed from the train, the way that
competitors' voltage driven systems read. The 13/16" x 3/4" amplifier board
contains a switch. Power comes from a 9 volt ALKALINE battery so that there is
full sound from the first turn of the wheel. Use a RAM 59 for rail
power.
