The SoundTraxx 829100 is the Tsunami SoundCar — a 16-bit digital sound decoder built for rolling stock rather than locomotives. It has no motor drive at all; it exists to give your cabooses, passenger cars, reefers and stock cars their own sound and lighting.
Because the sound comes from the train instead of the engine, you get running sound that moves down the consist: clickety-clack over the rail joints, flange squeal on curves, brake cylinders and coupler clank. SoundTraxx suggests roughly one SoundCar per third or fourth car rather than one in every car.

Does this go in a locomotive?
No. The SoundCar has no motor drive — it is made for the cars behind the engine. Put a Tsunami2, Blunami or Econami in the locomotive and a SoundCar in the train.
Do I need one in every car?
No. SoundTraxx recommends about one per third or fourth car. The effect is a train that sounds alive along its length, not a row of identical speakers.
Which cars is it for?
All rolling stock. Cabooses, passenger and cab cars, reefers and stock cars. The generator behaves differently by car type and the clickety-clack is set by axle count, so it can be tuned per car.
Is it a Tsunami2?
No. It is the Tsunami SoundCar — 16-bit sound, but its own product built for rolling stock, not a Tsunami2 variant.
Is a speaker included?
No. Use any 8-ohm speaker that fits the car.
