@Leucrotta To be fair, light-rail/subway trains I've ridden basically /anywhere/ else also don't have that noise. :-/
BART is just hella old and a bit badly designed because of the track screeching. (Which has been a thing as long as I've been alive at least, growing up in the Bay Area.)
@emanate okay, fair, this is the Empire’s Good Shit, but having the train sound horrible would be very lives in universe and it’s not like recording this terrible noise is difficult to do.
