i noticed that with most of the E400Hs that Abellio Stagecoach Metroline etc. have they make this whirring noise when stationary i narrowed it down to the fact that it is normal but not sure the purpose of it it's definitely not the coolant cos that's loud and the regen only happens when the driver slows quickly at a certain speed Anyone Know What it might be? p.s sorry if this is in the wrong place I'm still getting used to this website 😅 it can be heard quite faintly from 1:21 youtu.be/BcW1vBIEkqU

I’ve always noticed this and quite like it as it makes them unique. It sounds sometimes like it’s over revving , is that the same noise you’re talking about ?
