Inspired by the map made by Bostonography for their post about the 100th anniversary of the Red Line in Boston opening (from Harvard Sq to Park St) I decided to see what the system would have looked like in the vernacular of the modern system map. The present system map didn’t come into being until the system-wide style modernization in 1967. Before then the maps didn’t use colors (or when they did it was different, as in the case where the “Red” line was colored blue). Lines were known by where they went, as in the Washington St subway or the Cambridge subway, or the Commonwealth Ave trolley.  The names were chosen (so the urban legend goes) because: Red Line went to Harvard (their school color being crimson), the Green Line went along the Emerald Necklace, the Orange Line went under Washington St which was in colonial times known as Orange St, and the Blue Line which went underwater.

So instead of just flashing a bunch of old maps that all look completely different, it made more sense to stick to one style and animate each year when the system was expanded (or contracted in many cases). I toyed with the idea of having text describing each change on the map but found that too confusing since you can’t control it for each slide (which I may create later).

Listed below are the changes to the system by year.  I refer to all lines by their present day names:

The MBTA of today is hardly recognizable from the system a century ago.  This says a lot about the willingness of Boston to change and adapt itself to survive.  The many extensions from 1971 to 1987 were funded by transferring funds from canceled highway projects to mass transit.  During the 1990s the subway was neglected in favor of expanding commuter rail.  These suburban extensions were never paid for and are a huge reason the MBTA is steeped in so much debt today.

Now if you are anything like me (and obviously you are or you wouldn’t be here) you want to be able to take in each slide like it’s a fine scotch. I’ve created a gallery of each slide below so you can see each one and track the changes. The gallery viewer also has a slideshow function which works just like the animation above.
