The goal: ride every MBTA rapid transit station in one day, fast enough for a Guinness World Record. There’s a self-running guided demo that tours the studio in seven chapters — rides, transfers, auto timing, buses and the Silver Line, backtracking detection, and sharing — all computed live from the real GTFS schedule.

T Run imports the official MBTA GTFS feed and compiles it into schedule tables. The route studio lets you click two stations, or drag along a line, to preview the path. Auto mode times the train against a Google street run for the same pair and puts the fastest first. Every leg shows its scheduled time, and coverage is counted from every station a ridden train passes.

Scheduled, estimated and observed times stay separate, and directed transfers and boarding restrictions are preserved. Plans export to JSON, CSV or Google My Maps.
