After three years, I have since moved out of the Boston area and have less willingness to maintain this site. I appreciate everyone's attention and feedback.
The source code is and will remain free and open source. If anyone would like to stand up their own server or continue on with the service, please feel free to contact me for any help. I will let this domain name lapse but would be happy to transfer it over to an interested party before it does.
Thanks for using BostonTrainTrack! Happy trails!
