Sound Question for the Bach Man

[Pacific Northern]

I have decided to buy some of the Spectrum Steam Sound equipped engines.

So my question is  which Bachmann Spectrum models use the "light steam" sounds, which use the "medium Steam" sounds and lastly which use the "heavy steam" sounds?

Thanks

The Bachmann 2-10-2 Light Steam loco I bought & equipped with a Soundtraxx Tsunami uses the Heavy decoder.  If you believe Soundtraxx, check their site for your loco & see what decoder it's listed under - light, medium or heavy.
