The Tsunami2 TSU-2200

The TSU-2200 is a versatile decoder that will easily fit into a wide variety of HO to S scale models. You will feel like you are in the cab with the crisp sound and interactive features that Tsunami2 decoders have to offer!


For added realism, you’ll love the reactive Dynamic Digital Exhaust (DDE) feature. When your locomotive is traveling across flat terrain and simply maintaining speed, you will hear your locomotive chugging along. But, when the locomotive encounters a grade and the engineer applies more throttle to get the train up the hill, the engine sounds will automatically react and reflect the increase of power needed to crest the hill. DDE accomplishes this by calculating the changes in strain or load on the motor and adjusting the exhaust to appropriately simulate the work the engineer would be doing to the throttle of the engine. This gives Tsunami2 the ability to create the most realistic experience possible.


The large selection of high quality sound effects include: 

  • 10 Exhaust Chuffs
  • Up to 12 Prime Movers in each sound profile 
  • Up to 12 Bells 
  • 90 Whistles
  • 40+ Airhorns
  • Additional couplers, dynamos, cab chatter and more!


Additional realism can be simulated by adding functioning locomotive and train brakes, injectors, power reverse, firebox flicker and more.


The TSU-2200 can simply plug into models equipped with a DCC quick plug. A 9-Pin JST to NMRA 8-Pin Wiring Harness (P.N. 810135) can also be use to plug the TSU-2200 into models equipped with an NMRA 8-Pin plug. The TSU-2200 can also be wired into a large variety of models.
