Wow that's super interesting. I'm glad that the MBTA is publishing more detailed stats so we can get super interesting visualisations like that. I'd be curious to see how the charts update as Boston fixes its recent delays.
Lots of interesting ways to explore throughout, anomalies, and congestion in here. I wonder which other transit agencies publish this quality and quantity of data.
The first graph presented is a take on E.J. Marey's graphical train schedule. You can do that with pretty much any agency that puts out a schedule (one of the D3.js examples uses the Caltrain info). A lot of agencies have standardized on Google's GTFS for this information.
The station entrance/exits can be harder to track unless you are required to tag off. In the Bay Area BART publishes this info, I think as an Excel file.
Realtime info varies wildly, but a number of agencies (including BART) have jumped on the GTFS Realtime bandwagon. Muni went with NextBus which used to have a publicly accessible API (and that use to "hide" very detailed info), but it looks like everyone's favorite conglomerate, Cubic, destroyed that when they acquired NextBus.
