Fitting Sound to Atlas MP15DC

[Steve Williams]

Looking at the possibility of fitting a sound decoder to my Atlas MP15DC (Southern Pacific). Now I understand that the engine is the EMD 645E non-turbo 8 cylinder (please correct if wrong). As the horns fitted have two trumpets, I am assuming they are the Wabco E2. Looking at the QSI sound files available on QSI Solutions website, there are loads that include the MP15 , and I can find a couple with the Wabco E2 horn. However, I can only find them with 12 cylinders and more. There doesn’t seem to be any with 8 cylinders (unless I have missed them). Can anyone advise what the correct sound file would be and also whether their after-market, Atlas suited decoder will fit the MP15DC. It does not expressly mention that locomotive?

I would also be interested in people’s views as to best options for sound decoder in this model.

Thanks in anticipation.
