This is slightly off-topic because it's not completely related to PTIS / GPS, but it is about real-time data and tracking...
I just finished another update to my train mapping app which fully integrates the live data feed from the North Station & South Station departure boards. (also nostalgically called Solari boards) Now my app will list the status ("Now Boarding", "All Aboard", etc.) for all departures. If it's a trip which doesn't have any GPS position, it will be listed under the section "trains for which the MBTA is not getting and/or sending position data" which you can show/hide as you like.
I have a question for you all... Would you like it if I could use the departure track number to make the train location even more accurate?
Here's my idea... If I can get the exact GPS locations of each North Station and South Station track - close to the bumpers - then when the Solari board says "Track 4" I would ignore the coach PTIS GPS position and instead map the train based on the actual location of that track. I've noticed the PTIS GPS positions aren't very good when the control coach's GPS antenna can't get a clear sky view because it's underneath the Garden at North Station for example.
What do you think?

The Blue Line is good for Lynn, and Lynn is good for the Blue Line.
