The Trainspotting.nyc website is taking an extended hiatus. The parsing engine requires a fairly robust hosting instance to run acceptably, meaning the site is expensive to run publicly. The project has borne a lot of fruit, having served as a good portfolio piece for getting employment with the MTA initially, then evolving into a monitoring tool. One instance of the engine still runs for my "digital signage lab" as well.
Trainspotting is a software engine that parses New York City Transit GTFS-RT data feeds to produce real-time arrival data for the entire subway system.
Static data is parsed to produce timetables and to show which trains are scheduled to stop at which stations. Advisories are likewise dispayed for lines and stations in real-time.
A responsive website with coutdown clocks, strip maps, advisories, and the location of trains within the system in real time was created with the engine.
The project was forked and is presently used as an internal monitoring tool at the MTA for various real time feeds.
