Everything, but the prime mower!? I suspect that you also left the bell and horn turned on. To me those are the best sound effects on sound decoders. That, plus chuffs in steam locos.
Either way, this just proves how subjective sound is. Everybody's different.
Sorry, I wasn’t very clear on that. I meant a lot of sounds that are grouped by default with the prime mover and activated by F8. (Again ESU) The bell and horn are left on F1&2. On a few of my switchers I will map the engine fan to a separate function button as well just to add some variety but only when I want it.
I’ve had people recognize an Alco but never heard anyone say “ooooh, nice traction motors!”.
