That 9car to Richmond I saw it on bartfanmas

@astrotrain53 I've seen it used only one other time - to get someone off the yellow tiles at the edge as the train was pulling in.

I've only heard the beep button when I ride BART. When and why do the trains have air horns as well?

@TheLyricsmaniac90 Your guess is as good as mine...
