As my esteemed friend from NZ mentions, there is a difference in original prime mover sounds, and ESU provides sound files for both. I have a C-420 sound file in my C-420, a C-424 file in my CN C-424, and C-425 files in my four C-425s.
If the correct wire is used and the connections are sound, wire pick-ups will be fine. My three RS-3s with wire pick-up have performed brilliantly and require no maintenance. I cannot say that for the wipers on the C-425s as they require occasional cleaning and tweaking to maintain sufficient pressure. I will be converting them to wire pick-up at some point, and all future additions to the fleet will have the same.
