An inbound (southbound) Red Line train arriving at Charles/MGH station in July 2019 The Red Line started on March 23rd, 1912, owned by MBTA or Mass Bay Transit Authority. The line started between Alewife & Ashmont or Braintree. Has 4 yards: Alewife on the north side; Cabot, Codman & Caddigan on the south side. Crossing over the Charles River @ the Longfellow Bridge between downtown Boston & Cambridge, as well as the Nesponset River on the Braintree branch. At Cambridge, they are numberous stations underneath Massachusetts Ave from Kendall to Alewife. The line goes split south of the JFK/UMASS station: every 10-20 minutes, every 10-16 minutes on weekdays & every 12-16 minutes on weekends further north. Current rolling stocks is 1700s (aluminum body),1800s (stainless steel) & a brand new 1900s & 2000s until 2151.

Note how the MIT campus does not yet exist in the background of this view from Boston to Cambridge, with the Harvard Bridge in the distance. This dates the image to before 1916. Also, note that the Cambridge Subway (Red Line) tracks on the bridge have yet to be connected to anything. This dates the image to before 1912.
Although this is my favorite route, it would be easier for them to do a shorter line like blue or orange line
