As part of my project to ensure that all commuter rail in Massachusetts is in OpenStreetMap, I've now finished the first part: All lines originating from Boston's South Station are now there. These include the Greenbush line, Plymouth line, Kingston line, Middleborough/Lakeville line, Providence line, Stoughton line, Franklin line, Needham line, Framingham/Worcester line as well as some related Amtrak.

Most of these lines were not in the OSM database at all, and had to be added, along with stations, road bridges etc. Existing lines still had to be cleaned up significantly. Additionally, I fixed some of the issues around Boston's North and South stations.

Next up are the lines from Boston's North Station.
