I went to MacArthur on Sunday and actually the BART employee's told me it stopped at 3pm, and wouldn't pick up again til 8pm. I figured I missed out but luckily they flagged me over 15 minutes later and said I'd be able to get on one for 10-15 minutes so thank you to the entire BART staff at MacArthur station for allowing me on. I edited 2 videos and will drop the second one later.
