As a recent convert from HO I am not up to speed on everything with On30. I just installed a HO sound decoder into my new Bachmann 2-6-6-2. Afterward I got thinking about the AMP loading. Can anyone tell me if HO decoders are suitable or will I burn them out?

Second I am looking for a sound decoder with sounds for a gasoline engine such as found in a railbus. Does anyone have experience with this?

Welcome, tgears1! I have done some installs for On30 steam and critters, and have only had one instance where overheating was a problem. Generally, the motors for our little narrow gauge locos are comparable with HO current draw. If possible, use an ammeter to measure the draw of your loco with the motor warmed up on your heaviest grade/load. Soundtraxx specifies .75 amps for the TSU-750, and 1 amp for the TSU-1000.

I have successfully used TSU-750 steam and galloping goose decoders in Bachmann 0-6-0 and GE 45-tonner chassis with great results. It helps to mount the decoder against a piece of brass to act as a heat sink, or the side of a brass loco cab or tender chassis. The larger TSU-1000s are no problem with the bigger locomotives like the 4-4-0s, etc.

I have a step by step guide on my website of one of my Tsunami installs here: http://members.cox.net/vgniner/workbench/dcc/dcc.html
