For later in 2013, I hope to make available in-depth data concerning MBTA on-time performance.
I’ve time-mapped the MBTA for the “New Perspectives” T Map Challenge. See the Time — Mapping the MBTA project page.
I’ve collected a number of historical maps of Boston, which are interesting for the extent to which they show the development of rail and trolley lines. I’ve also traced out inactive rail rights of way in modern maps. See the Transit Rights of Way Project page.
For the year 2007, I compiled data about escalators on the MBTA system. For more information see the Elevator & Escalator Project page.
