MTA Technically the MBTA replaced the MTA it is legally not a descendant but a new agency to which all of the assets of the old agency were transferred The MTA was financed under the authority of the Boston Metropolitan District no relation to the Metropolitan District Commission which persisted until all its bonds were retired in the late 1980s or early 1990s check US Census Bureau s census of governments for details long after the MBTA took over from the MTA Many parts of what we now think of as the MBTA system were actually started under MTA jurisdiction A good external reference is Scott Moore s NETransit site Shorter disambuator How about we move all the station and line pages from Name Massachusetts Bay Transportation Authority to Name MBTA so the title line isn t dominated by the disambiguator 2051 20 Dec 2004 UTC Having typed the long form seemingly ten zillion times in nearly as many articles this sounds like a good idea to me As far as I m concerned have at it But know now that there will be a lot of links to edit 21 26 20 Dec 2004 UTC Excellent Resource This site MBTA Resources is a fantastic collection of Boston transit information down to station by station histories and photos I suggest it be added to the external links section of the article 12 24 14 Jan 2005 UTC If you think so you re welcome to add the link no need to ask for consensus on an uncontroversial edit this is Wikipedia after all 12 52 14 Jan 2005 UTC Did it 00 07 15 Jan 2005 UTC Track connections between subway lines As far as I know there are no connections direct OR indirect between the lines The Red Line MAY have a connection to the Commuter Rail at the Cabot Yard or at a track near Neponset just north of the Neponset River but I doubt it The Blue Line has no connections to any other rail lines I think the Orange Line has a connection at Wellington and the Green Line has only Riverside So there MAY very indirect connections between the Red Orange and Green but they are never used except in emergencies like when the Green Line flooded and Commuter Rail trains served Riverside Just checked a few sources A June 2000 track map shows no connection at Wellington or anywhere else on the Orange Line Same for the Red Line Of course it also shows no Green Line connection at Riverside and I know that exists but is usually fenced off The track I remember at Neponset is a dead end Java At Cabot Yard Red Line and South Bay Yard Commuter Rail the two systems are totally separated lookign at aerials on that same site So the only one remaining to check is Wellington Now the Orange Line USED to connect via Everett Shops as did the Green Line via surface tracks under the El And the Blue and Red connected over the Longfellow Bridge and there may have been a connection at Eliot Street Yard in Harvard connecting the Red Line to the streetcar line to Watertown and thus the Green Line but I m not sure about that But at one point the Longfellow Bridge track did connect to other streetcar tracks And I think I found a connection north of Wellington on aerials at but I m not sure shouldn t be too hard to spot from the Commuter Rail harder from the Orange Line because of the unused east track if it exists But even if there is an Orange Green connection via Commuter Rail and fairly direct at that using the Grand Junction Line I would very much doubt it gets any use So how do you figure all those nice new Red Line cars were delivered from Barre Vermont Ah here we go Blue has none Red has one at JFK UMass Orange has one at Wellington last used ca 1981 and Green has one at Riverside None appear to be used at the present time It would be rather misleading to suggest that there are in fact connections How s this Except between the Red Line and Ashmont Mattapan High Speed Line there are no track c
