Pictures tell 1000 words.
This line was to tag off the Caltrain at Millbrae before we could enter the BART system. 10 people had already tagged off before I took this photo. 8 people in total could not complete the tag off transaction, go 30 yards to the BART faregates, tag into the BART system, before finally the BART train that was on the platform when we arrived, departed without us. Instead, we waited for the next train, 15 minutes later. 2 hours of lost time from one Caltrain, for lack of more readers, more appropriately placed readers, or a better software setup that would tag us off Caltrain when exiting BART. Multiply this by dozens of trains per day, 200+ work days per year.
I hadn't seen lines like this before - but February has brought with it the end of the paper eight ride tickets.
