I have mentioned this previously but I will emphasise it again. On the Class 377, 387 and 375, Please. Turn. The rain noises. Down. The sound itself isn't the problem, it's the VOLUME of it. It is obnoxiously loud and obscures more important noises such as the safety systems, the run sounds and the traction motors. I'm not asking for anything to be swapped or changed, just PLEASE TURN IT DOWN. It's not a problem on most other trains and it's been like this for far too long. Please just turn the volume of it down or give us the option to do it ourselves.
