Thank you Hunt - you have saved me a quite a bit of time, money and frustration

I recently purchased a Bachmann Spectrum On30 Heisler - sound ready only with factory built in speaker. Does anyone know if I install the SoundTraxx 884008 TSU-21PNEM Tsunami 2 Sound Decoder, will it work?

I'm really unsure $80 bucks for this module (plug and play). In comparison to over $200 for a normal one (which includes installation).  I may need to consider It a bit more - unless some out there has done this before and it has worked.

I recently purchased a Bachmann Spectrum On30 Heisler.  Unfortunately the plug and play sound module is no longer being manufactured and I cannot find anyone with stocks. Does anyone know if I can substitute Buchmann's #44959 sound module for 0-6-0 into my Heisler.

Yep - that looks like it will work on tight curves....thanks heaps

Hi everyone - New member and my first post here.  Can anyone inform me what the minimum radius the On30 2-6-2 Baldwin Trench Loco will comfortably run around.  Currently I have an 18" radius on my layout.  I live in Australia and wanting to order one from the States – it's a long trip back to the store if it doesn't work on my layout
