Ton,
The Tsunami sound decoders sound awesome. The folks at soundtracks are in Durango, so they know exactly what a K sounds like.
My Dad was a train enthusiast all of his life. My Grandfather was a patent Lawyer, and had written the patent on a pump designed to pump water out of the mines. When the pumps were installed near Central City, they didn't work correctly, and the inventor had gone to Europe. My Grandfather was the person who knew the most about the way the pumps were supposed to work, so they sent my Grandfather to Central City to help get the pumps working, and he took his family along.
So my dad, as a kid, was exposed to Central City Colorado, in the twenties, when there were three or four narrow gauge railroads in the vicinity, and he was interested in narrow gauge for the rest of his life. Dad wasn't a tinkerer, or a builder, ( I got that from my Mom's family the Vandyke s, who were Millers and fancy carpenters) ; and didn't find his way into narrow gauge modeling until Lgb started selling large scale stuff in the states .
My dad was a professional Forrester, and when he was in graduate school, he worked in the woods with Shays, and that is where my logging interest developed.
If you have any questions on the Tsunami install the On3 group @ Yahoo has regular discussions on that subject. I lurk there, as I have an On3 CN60 shay, and a Bachman On30 Climax with sound, that I intend to stretch to 0n3 ( My dad raised me up looking at 3 foot gauge track, and the narrower stuff doesn't quite look right to me. I have been wanting to so something simple with the ON3, but after 44 years of HO and 32 years of HOn3, the space needs of O scale keep putting me off.
