Man nothing to me is more relaxing than the chug chug idle of non turbo EMD, turbo units sound awesome as well, but as someone who has been rocked to sleep by a 16-567 in a GTW GP9r waiting for customers to be ready for a switch there is nothing quite like it haha.
Love it! I ran the engine rooms of EMD powered towboats for forty one years, and there's no better "fall asleep music" than the engines at idle, with the boat gently buzzing, while you're standing by. :-)
This is great. This would be perfect for all my model EMD SD 40-2 on my layout & train yard. You're so right this is relaxing to hear this engine idling. Beautiful sound. 🎧🙂
Good sound effects for model train layout especially for my kiwi rail locos idling on my shelf end to end layout cheers from Bruce.blenheim south island new Zealand
Well, the Class 66 was produced by EMD using the 12-710 prime mover, so it's not exactly the same but it does sound somewhat similar. The 710 prime mover was used on the SD70 series though.
