did i record something rare? 

sorry for camera being weirdly tilted
this is bart in san francisco, and the video was recorded on 10th of september, at around 21 hours. announcement about it being last red line train kinda confused me, as it was playing when all trains were arriving, so i assume announcement thing just broke. i was told that before this not in service train there was another old train that did actually stop on the station, and announcement was made for it (as after that there would be no more old trains in service), but for some reason right after it there was another old train that is recorded on this video
i should mention im not 100% sure what happened, so information i provided here might be wrong
