Red Line Signage

The Red Line is a rapid transit line operated by the MBTA running roughly north-south through Boston, Massachusetts into neighboring communities. From the northwest, the line begins in Cambridge, Massachusetts at Alewife station, near the intersection of Alewife Brook Parkway and Route 2. The line passes through downtown Boston, with transfers to the Green Line at Park Street station, the Silver Line at South Station, and the Orange Line at Downtown Crossing. South of downtown, the line splits at JFK/UMass station, where one branch provides service to Braintree station and the other to Ashmont station. A connection to the Ashmont-Mattapan High Speed Line extends the reach of the Ashmont branch to Mattapan station.

Regular fare is $1.70 when using a CharlieCard or $2.00 when using cash or a Charlie Ticket, regardless of point of boarding or departure. Exit fares on the Braintree extension were discontinued in 2007. Approximate travel times to or from Park Street station (excluding headways) are as follows: northbound to Harvard station, 11 minutes; Alewife station, 20 minutes; southbound to JFK/UMass, 8 minutes; Ashmont station, 17 minutes; Braintree station, 28 minutes.

History

The Red Line was the last of the four original Boston subway lines (Green, Orange, Blue) to begin construction. The section from Harvard station and Eliot Yard connecting to Park Street station and the Tremont Street Subway opened on March 23, 1912. At Harvard, a prepayment station was provided for easy transfer to streetcar routes operating in a separate tunnel (now the Harvard Bus Tunnel). Opening of the line required construction of the Cambridge Tunnel just beneath Massachusetts Avenue and Main Street from Harvard onto the (now historic) Longfellow Bridge. The line occupied a previously constructed rail right-of-way in the center of the bridge. On the Boston side of the bridge, the line briefly transformed into an elevated railway, rising over Charles Circle and connecting to another tunnel dug through Beacon Hill to Park Street. Further extensions (built as the Dorchester Tunnel) to Washington Street and South Station opened on April 4, 1915 and December 3, 1916, with transfers to the Washington Street Tunnel and Atlantic Avenue Elevated respectively. Further extensions opened to Broadway on December 15, 1917 and Andrew on June 29, 1918, both prepayment stations for streetcar transfer. The Broadway station included an upper level with its own tunnel for streetcars, which was abandoned in 1919 due to most lines being truncated to Andrew. The upper level has since been incorporated into the mezzanine.

Next came the Dorchester Extension, now known as the Ashmont Branch. The branch followed a rail right-of-way created in 1870 by the Shawmut Branch Railroad. In 1872, the right-of-way was acquired by the Old Colony Railroad to connect the main line at Harrison Square with the Dorchester and Milton Branch Railroad, running from the Old Colony at Neponset, west to what is now Mattapan station. The New York, New Haven and Hartford Railroad succeeded Old Colony in operating the branch and rail passenger service ceased in anticipation of the MTA expansion on September 4, 1926,

The MTA opened the first phase of the Dorchester Extension to Field's Corner station on November 5, 1927. Service ran south from Andrew station, turned southeast to the surface, and ran along the west side of the Old Colony mainline in a depressed right-of-way. Columbia station and Savin Hill station were built on the surface at the sites of former Old Colony stations. The remainder of the extension opened to Ashmont station and Codman Yard on September 1, 1928, and included a station - Shawmut - where there had been no Old Colony station due to the relatively close proximity to Fields Corner. The first phase of the Ashmont-Mattapan High Speed Line opened on August 26, 1929, using the rest of the Shawmut Branch right-of-way, including Cedar Grove station, and part of the old Dorchester and Milton Branch.

The color red was assigned on August 26, 1965 to what had been called the Cambridge-Dorchester Tunnel and marked on maps as route 1. The color was chosen because the line ended at Harvard University, whose school color is crimson, a shade of red.

The first section of the South Shore Line opened on September 1, 1971. This line branched from the original line at a flying junction north of Columbia and ran along the west side of the Old Colony right-of-way (since reduced to one track), crossing to the east side north of Savin Hill. Its northernmost station was North Quincy, with two others at Wollaston and Quincy Center. The rest of the line, the Braintree Extension (first planned by the Boston Transportation Planning Review) to Braintree station, opened March 22, 1980, and the intermediate station at Quincy Adams station opened on September 10, 1983.

The first part of the Northwest Extension, the relocation of Harvard station, was finished on September 6, 1983. During construction, several temporary stations were built at Harvard Square. The old Eliot Yard was demolished; Harvard's Kennedy School of Government now sits inside the retaining walls built for the railyard. Subsequent extensions to Porter station, Davis station on December 8, 1984, and Alewife station on March 30, 1985 brought the Red Line to its current extent. There were possible plans to extend the Northwest Extension from Alewife to Lexington via an abandoned rail right-of-way, but these plans never materialized. A platform on the South Shore Line opened at JFK/UMass (formerly Columbia) on December 14, 1988.

Platforms on older stations were lengthened in the late 1980s to allow six-car trains, which first ran January 21, 1988. During the expansion, the MBTA invested in an Arts on the line public art program.

In 1968, letters were assigned to the south branches - "A" for Quincy (planned to extend to South Braintree) and "C" for Ashmont. "B" was probably reserved for a planned branch from Braintree to Brockton. As new rollsigns were made, this lettering was phased out. In 1994, new electronic signs included a different labeling - "A" for Ashmont, "B" for Braintree and "C" for Alewife. [2]

Operations and signalling

The line used trip-stop wayside signalling for the Ashmont and Harvard branches until the mid-1980s, while the Braintree Branch was one of the earliest examples of Automatic Train Control (ATC). The Alewife Branch was built with ATC, at which point the remainder of the line was upgraded to ATC as well. The line was under local control at towers until 1985 when an electromechanical panel was completed at 45 High St. This was replaced in the late 1990s with a software-controlled Automatic Train Supervision, using a product by Union Switch & Signal, subcontracted to Syseca Inc. (now ARINC), at a new theater at 45 High St. Subsequent revisions to the system were made internally at the MBTA.

The shortest scheduled headway ever run on the Red Line is most likely the 1-3/4 minute interval in the schedule published in 1928. Ridership peaked on the line around 1947, when passenger counters logged over 850 people per four car train during peak periods. The newer ATC signalling was designed to higher safety standards, but the particular design of the block layout in the downtown area reduced the capacity by 50% over the previous wayside signalling system. The net loss of capacity measured in cars per hour has not been rectified, although at the same time the platforms were lengthened to run 6-car trains which are now operated on a longer headway. Additionally, the shifting between speed codes that is inherent in an ATC system near capacity caused peak period energy consumption to skyrocket, and accelerated the decline of the 01400 series fleet.

Accessibility

Most, but not all, Red Line stations are wheelchair accessible. See also MBTA accessibility.

Equipment

The Red Line is standard gauge heavy rail. Trains consist of mated pairs of Electrical Multiple Unit cars powered from a 600 VDC third rail. Trains run either in 4-car or 6-car sets.

Rolling stock is stored and maintained at the Cabot Yard, near the Broadway station in South Boston. The connection to this yard is at the junction where the two branches split, near JFK/UMass station.

Two basic types of cars are in use today:

Aluminium-bodied cars

Three series of older aluminum-bodied cars built by Pullman-Standard and UTDC. The older two series of this batch, the 01500 and 01600 series, were built by Pullman in 1969-1970. The 1700 series was built by UTDC in 1988. These cars seat 62 to 64 customers and approximately 132 cars are in active service. All cars in these series are painted white with red trim and use manually-operated exterior signs.

All three groups of these older cars (units 1500 through 1757) use traditional DC traction motors with electromechanical controls manufactured by Westinghouse and can inter-operate among the three series. The 1500 and 1700 series cars could operate as singletons, but in practice, are always operated as mated pairs. The 1600 series could only operate as mated pairs.

Stainless steel-bodied cars

One series of newer stainless steel-bodied cars built by Bombardier from components manufactured in Canada and assembled in Barre, Vermont. These cars seat 50 passengers and 86 cars are in active service. An automatic voice synthesis system provides station announcements; the announcements are also displayed on LED signs in each car. These cars are stainless steel with red trim and use yellow LCD exterior signs. Unlike the previous series, these train cars originally had red cloth seats (in contrast to the black leather seats of other models), but in the early 2000s, the cloth seats were replaced with black leather seats.

Known as the 1800 series, they were built in 1993-1994. These newer cars (units 1800 through 1885) use modern AC traction motors with solid state controls manufactured by General Electric, can only operate as mated pairs, and can not interoperate with the older three series of cars.

An automated voice announces each stop and the terminating station for each of the newer trains. These announcements, however, are sometimes wrong so riders should take note of the signs in the stations.

Art and architecture

Newer aboveground stations (particularly Alewife, Braintree, and Quincy Adams) are excellent examples of brutalist architecture.

The Kendall station features an interactive public art installation by Paul Matisse called the Kendall Band, which allows the public to activate three sound-producing machines utilizing cranks on the wall of the station.

Advertising

In between South Station and Broadway, and also between Harvard station and Central Square, there is an advertisement in the form of a zoetrope. The speed of the train along with strategically timed strobe lights make the individual frames look animated. There are similar advertisements in parts of the New York City Subway, Washington Metro and the Bay Area Rapid Transit.

In popular culture

• In 1944, Tom Lehrer wrote a song called Boston, (a parody of the song Mother) whose lyrics list stops on the Red Line and an appropriate Boston accent when necessary:

H is for my alma mater, Hahvahd.
C is Central, next stop on the line.
K is for the cozy Kendall station, and
C is Charles, which overlooks the brine.
P is "Pahk" Street, busy Boston center, and
W is Washington, you see.
Put them all together, they spell…HCKC-PW…which is just about what Boston means to me!

• The tunnels of the Red Line have a cameo in the 1936 H. P. Lovecraft novella "At the Mountains of Madness," in which a character rattles off the stops from South Station to Harvard to calm himself as a nameless horror chases him through a cave in Antarctica. "South Station Under - Washington Under - Park Street Under-Kendall - Central - Harvard - " Park Street also shows up in his 1927 story "Pickman's Model."

• In the 1997 film Good Will Hunting, there are several scenes filmed on the Red Line, including across Longfellow Bridge and between Savin Hill and JFK/UMass.

• The Red Line features heavily in the 2006 film The Departed. Brief takes of the train in Dorchester, just south of the Dorchester Tunnel, and crossing over the Neponset River on the Anderson Bridge are used as transitional shots. Later in the film, several of the main characters engage in a cell conversation while riding the Red Line from Park St. to South Station, despite the fact that this section of tunnel has no cell service. There are also shots of the Park Street station and South Station exit.
