Your "1993 Map" is nothing of the sort! Newburyport , Greenbush, Plymouth line didn't exist then (or just as worn out single track freight lines to Plymouth and Newburyport), and the Fitchburg line was mostly single track Ayer to Waltham.
Thanks for your feedback stevefol! I assume you refer to this map: https://www.dbperry.net/MBTA/maps/mbtac ... etwork.pdf
While slightly off topic from this thread, I'll offer some background on what it is and where I obtained it.
While over at the South Station dispatch theatre - commonly known at CTEC - back in late 2003, I saw a poster under a frame on the wall. While admiring it and studying it, someone with an office there said something to the effect of, you know, I think we have some of those hanging around. He found a rolled up set of them and offered me one! I brought it home, scanned it, and posted it. That's how it came to be in my possession.
1) I have no idea who created it or why, other than it saying "Thomas K. Dyer, Inc." which was a well-known engineering consulting firm that did considerable work for the MBTA back in the day.
2) Since I didn't create it, and I don't have any contemporaneous other track charts, I cannot vouch for its accuracy.
3) The track chart certainly appears to show some aspect of track arrangement and clearly does not presume to represent a map of current service. It also doesn't represent MBTA or MassDOT (or its predecessors) ownership of rail lines, since we know that much of the trackage shown on the map was owned by CSX and others in 1993.
4) With regards to the Old Colony network, my assumption is this track chart depicts what was planned to be implemented as part of the restoration of service, which was still at least a few years off for most of the Old Colony and many years in the future for the Greenbush.
5) As to Newburyport, I agree, the inclusion of the Newburyport draw appears odd, since I believe that was abandoned in the early 1980's. I'm guessing the rest of the Newburyport depiction is similar to the Old Colony depiction - what was intended to be implemented in the coming years.
6) I'm not as familiar with the track arrangement or history of the Fitchburg line, so I'll defer to your assertions on that one.
Glad you enjoyed it!
