I said "then give them what they want, change the sound files; record the engine sounds of a traditional locomotives with air whistles and give the traditionalist original sounds.

This isn't as far out of an idea as it first appears. Automobile manufacturers have been playing this trick for a while now. Some install resonators in the exhaust that are below the floorpan or dash to give the engine more of a rumbly sound. Others just pipe augmented sounds through the stereo system even when the radio is turned off!
