So plan on getting to the Boston stations 5 to 10 minutes earlier than you usually do now once they are installed.
Sorry, what are you advising the 5 to 10 minutes for?
From pictures, I'd expect something like 10-abreast simultaneous throughput, which is more than can walk abreast out a platform. In other words, the fare gate barriers will likely have more throughput than the barrier-free platform itself (and on par with the sliding doors to the waiting areas). Since trains stagger in departure, I'd expect that as long as first boarding calls are spaced 1 min apart (like they usually are) the "initial clog" for any one trip is unlikely to last more than a minute and unlikely to overlap between any 2 trains.
Swag that a cycle at a gate is 6 seconds: 1) approach, 2)pay fare, 3)gates open, 4)walk through, 5)exit gate, 6)gate closes, repeat. Every 10 gates can process 100 people in every minute. The picture suggests that they'll fit probably 10 on each side (Summer, Atlantic) and I'd have to bet another 30 "in the middle". 40 gates would process 400 in a minute and a whole 1400 person train in 3minutes 30 seconds.
All London commuter rail is now tap-in / tap-out, where your phone,, tap card, or tap-enabled bank card can be tapped on a NFC sensor, or you insert your paper ticket (mag stripe) into a reader. Works just like Charlie Card/Ticket on the Subway, except the fare media is more varied. it didn't add any time that I could detect to my trail trips. How many extra minutes do you allow for that? Maybe an extra .5 minutes?
In England you use your fare media for platform access. It is a guarantee that you've at least paid your "Zone 1A" fare (just like the human inspections today).
People will simply have to either use the ticket or card media the have, or be sure to display the QR Code on their phone (instead of the dancing-colored-bars view they show conductors)
