I recently purchased the 1:20.3 Narrow Gauge 55 Ton Three-Truck Shay to display only (all I want to do is show it off) and am confused as to what gauge / scale straight track to set it on.  Thank you in advance for your detailed advice.

I recently purchased a second new HO Shay with factory DCC and Sound.  I have been able to change CV's with the exception of the locomotive address, both 03 as delivered.  I'm using a Digitrax DCS 100 Command Station Booster with a DT402R Throttle.  I've tried everything I can think of from the Tsunami Steam Sound Users Guide to Digitrax on youtube and I can't get either to change.  Thank you in advance for your advice.

What is the model number of the HO Spectrum 80 Ton 3 Truck Shay Locomotive: Painted, Unlettered Steel and/or Wood Cab, with Onboard DCC and Sound with coal tender please?

I would also appreciate it if you could provide me a site or source where I may find the model numbers and detailed descriptions of the other HO Spectrum Shays.  

Thank you in advance.
