I’ve noticed that when in the cab of the 395 and when a 375 passes by, the 375 makes a strange grating sound. It doesn’t sound like rail squeal or junction wheel noise. I don’t know how else to describe it, but it has happened every time a 375 in motion passes the 395 and it’s more noticeable if the 395 is stationary when a 375 passes.
I also noticed an odd noise when applying some brake to the Class 66 in the service that it has on SEHS. Some in cab grind noise as the brake needle moves
