Some parked Green Line LRVs at Lechmere. There's a loop here to return on the opposite track. This line is being extended to Somerville and Medford. At one time it did street running, but that was terminated sometime in the 1950s. I never knew about that except for some traces here and there of tracks in the street. Now they're pushing the line over to the MBTA/PAR tracks and using that to extend the line by crossing Cambridge Street, located behind the camera and then between some old factories and warehouses on what was once some sidings in the industrial area to bring the line on to the ROW.

Red Line Subway at Park Street.

Park Street is one of the oldest subway stations and the line connecting is the oldest subway tunnel in the US, 2nd from London. The Green Line trolley line connecting from Boylston Street station, located just down the block on the corner of Boylston and Tremont, has the tightest curve of any system in use today and in a tunnel. When the "T" orders new equipment, they have to be specific about the bogie radius, otherwise, the trolleys get stuck and derail. This occurred with the "new" Breda LRVs that came in about 20 years ago, and also happened recently with some new equipment. Someone messed up yet again and a trolley derailed on the curve and got stuck in the tunnel. Ooops!
Park Street is also a junction with all the trolley lines coming together. There's the Lechmere/North Station line coming in and that continues on down Boylston Street with branches for other places located farther out. In Park Street, there's also the Beacon Street line with on-surface crossing over between. You can take a trolley between Lechmere and Beacon Street as well as take one going the other way. This is the busiest stations on the system.

The Red Line is one of the newer lines, dating back to 1910 or so. That line was known as the Cambridge Subway because it terminated there. Today, that end is extended to Alewife where it terminates at the Alewife Brook Parkway. This line runs under then on the former ROW of the Fitchburg Railroad. The commuter, and some freight, still run above the subway and then passed the terminus at that end. When this station was put in, it broke the Lexington Branch and a large double-wye was removed that was once protected by a big array of semaphore signals. I remember seeing that before they were removed.
The Red line continues on through stops at Washington Street (Downtown Crossing), South Station, and then on to Dorchester and further on the Quincy and Braintree. These latter two stops were added in the 1970s when the line was extended and it runs on the former New Haven Old Colony Line ROW to these locations.

The Redline comes out of the subway at Kendall Sq. Cambridge and crosses the Charles River to Boston over the Longfellow Bridge. This bridge has been substantially rebuilt, but preserved (yay!) since these shots were taken.
At Ashmont, the Redline connects with an actual trolley extension using PCC trolleys that have been restored. They run from Ashmont to Mattapan Square.

This standalone trolley line was created back in 1915 or so when the NH gave up the line to Mattapan and sold it to either the Metropolitan Transit Authority, or Boston Elevated and the line was built.
