Reference the latest MTH MP15ACs and just-released GP38-2s...do they use the same sound sets??
Should they sound alike based on the diesel engine in each??
Please advise...thanks for your kind and generous response.

Yes, they will sound alike. Both used the 645E prime mover.
Actually I "think" they do sound a bit different but I don't know that the small speakers in our models could replicate it. The MP15s (and the SW1500s before them) have V12 Roots-blown 645s whereas the GP38s have V16 Roots-blown 645s. Once-upon-a-time we rode behind #611 to Louisville and were pulled backwards into town by an SW1500 coupled to the open gondola. I listened (at close range) to that V12 pulling hard and it did seem to have an odd&different deep throbbing sound than I have ever heard from a '38. Or it was because I was maybe 20ft from the stacks. 
Thank you.
