Hello,
I have recently built a tracker for MBTA subway trains, and it has come to my attention that multiple Green Line cars have consistent tracking issues. 

  • 3632 - Car will track as 3624, sometimes adds 3624 to the consist, and sometimes makes whatever 3624 is with show as a three-car set. Will also cause 3624's consist to not track
  • 3713- Sometimes shows up as a B train, sometimes shows up as a PCC (no matter the line or location)
  • 3677- Will often track as paired with 676 when it's not. If 676 is active, it will show as tracking in two places at once 
  • 3659 - Will regularly track as a single car (only when leading)
  • 3607 - does not track
I'm not sure what can be done about this or if this is even an API/Tracker issue. There are also many cars that have tracking issues that only appear when coupled to specific other cars. It is also a common occurrence that cars that are coupled will show up as two different trains. 

Thanks,
Quinn
