The Massachusetts Bay Transportation Authority (MBTA) operates heavy-rail, light-rail, and bus transit services in the Boston metropolitan area, collectively referred to as the rapid transit, subway, or the T system.[1]
The color-branded lines consist of three heavy-rail lines (Red, Orange, and Blue), one branched light-rail system (Green), and a short light-rail line (the Ashmont–Mattapan High-Speed Line, colored as part of the Red Line). All except the Ashmont–Mattapan line operate in tunnels in the downtown area, but no route operates entirely underground. Only 26 out of the system's 133 stations are located underground. The five branches of the Silver Line bus are also shown as part of the rapid transit system. Three branches operate underground as bus rapid transit and charge rapid-transit fares; two branches operate entirely on the surface and charge lower bus fares.
The section of the Tremont Street subway between Park Street and Boylston Street stations, now on the Green Line, opened in 1897, making it the oldest transit subway in the United States still in use. (Only the short-lived Beach Pneumatic Transit demonstration line in New York City was built before.)
History
Opened in September 1897, the four-track-wide segment of the Green Line tunnel between Park Street and Boylston stations was the first subway in the United States, and has been designated a National Historic Landmark. The downtown portions of what are now the Green, Orange, Blue, and Red line tunnels were all in service by 1912. Additions to the rapid transit network occurred in most decades of the 1900s, and continue in the 2000s with the addition of Silver Line bus rapid transit and planned Green Line expansion.[citation needed] (See MBTA History and MBTA Future plans sections.)
Streetcar congestion in downtown Boston led to the establishment of subways and elevated rail, the former in 1897 and the latter in 1901. The Tremont Street subway was the first rapid transit tunnel in the United States. The grade-separated railways added transportation capacity while avoiding delays caused by intersections with cross streets.[2] The first elevated railway and the first rapid transit line in Boston were built three years before the first underground line of the New York City Subway, but 34 years after the first London Underground lines, and long after the first elevated railway in New York City.[3]
Various extensions and branches were added to the subway lines at both ends, bypassing more surface tracks. As grade-separated lines were extended, street-running lines were cut back for faster downtown service. The last elevated heavy rail or "El" inter-station segments in Boston – with the exception of the Red Line's still-active elevated tracks, connecting Charles/MGH station over Charles Circle to the Longfellow Bridge and the Cambridge Tunnel's northern portal – were at the extremities of the Orange Line: its northern end was relocated in 1975 from Everett to Malden, MA, and its southern end was relocated into the Southwest Corridor in 1987. However, the Green Line's Causeway Street Elevated remained in service until 2004, when it was relocated into a tunnel with an incline to reconnect to the Lechmere Viaduct. The Lechmere Viaduct and a short section of steel-framed elevated at its northern end remain in service, though the elevated section will be cut back slightly and connected to a northwards viaduct extension in 2017 as part of the Green Line Extension.
System
Lines
The rapid transit lines consist of 3 heavy-rail lines, 2 light-rail lines, and an underground bus rapid transit line.
The traditional heavy-rail lines include the Blue Line, which is a former trolley line running from Revere to downtown Boston; the Orange Line, which was converted from an elevated line running from Roxbury to Malden; and the Red Line, running from Cambridge to either Ashmont or Braintree.
The light-rail lines include 4 Green Line branches which terminate in Brighton, Brookline, Newton, and Roxbury, and the solely Red Line-linked Mattapan High Speed Line.
Three branches of the Silver Line, the SL1, SL2, and SL3, operate in tunnels for part of their length, with direct transfers at South Station. These three lines use the higher subway fare, while SL4 and SL5 follow bus fare rules.

Coverage
All four subway lines cross downtown, forming a quadrilateral configuration, and the Orange and Green Lines (which run approximately parallel in that district) also connect directly at two stations just north of downtown. The Red Line and Blue Line are the only pair of subway lines which do not have a direct transfer connection to each other. Because the various subway lines do not consistently run in any given compass direction, it is customary to refer to line directions as "inbound" or "outbound". Inbound trains travel towards the four downtown transfer stations–Park Street, State Street, Government Center and Downtown Crossing–and outbound trains travel away from these hub stations.[4]
The Green Line has four branches in the west: "B" (Boston College), "C" (Cleveland Circle), "D" (Riverside), and "E" (Heath Street). The A branch formerly went to Watertown, filling in the north-to-south letter assignment pattern, and the E branch formerly continued beyond Heath Street to Arborway.
The Red Line has two branches in the south—Ashmont and Braintree, named after their terminal stations.
Colors
Originally, transit lines in the region only used geographic names; though numbering was added to public maps in 1936. The three heavy-rail lines were assigned numbers 1, 2, and 3; what is now the Green Line was assigned different numbers for each branch. However, riders generally continued to use the geographic names.[5] Colors were assigned on August 26, 1965 as part of a wider modernization under design standards developed by Cambridge Seven Associates, and have served as the primary identifier for the lines since then.[6] The numbers for the heavy-rail lines and the Mattapan Line were retained in public information until 1966.[5] In 1967, the then-current five branches of the Green Line were lettered A through E.[5]
Cambridge Seven originally intended to use red, yellow, green, and blue for the four lines. However, yellow proved unsuitable, since some patrons would have difficulty reading yellow text on a white background; orange was substituted, and yellow eventually was used for the MBTA bus service's visibility markings and signage.[7] When sketching design concepts, Peter Chermayeff labeled the subway-surface light rail routes as the Green Line because they run adjacent to parts of the Emerald Necklace park system. The East Boston Tunnel became the Blue Line because it runs under Boston Harbor, and the Cambridge-Dorchester Tunnel became the Red Line because its northernmost terminus was then at Harvard University, whose school color is crimson. According to Chermayeff, the Main Line El "ended up being orange for no particular reason beyond color balance."[8] The MBTA and transit historians later claimed that orange came from Orange Street, an early name for the street that ran southwards down the Boston Neck to connect the Shawmut Peninsula to the mainland, for what is now part of Washington Street.[9][10][7]
When the switch to colored names was made, the MBTA planned to color bus rollsigns and bus stop signs to match the destination station of the route.[11] However, that scheme was never implemented.[citation needed]
Stations
The MBTA rapid transit system consists of 133 stations, with another 7 in construction as part of the Green Line Extension project in Somerville.
Rolling stock
The MBTA is in the process of replacing its entire fleet of Red Line and Orange Line cars, which are some 30 years old, by 2023. The Blue Line cars were replaced in 2008. The Green Line has a variety of vehicles, some dating back to 1986, with the latest batch delivered in 2019.
The four transit lines all use standard rail gauge, but are otherwise incompatible. Blue Line trains can run on Orange Line tracks, but can't be used for revenue service because the two lines have different platform heights. Orange Line cars are too long to negotiate the tight turns of the Blue Line.[12] However, this limited compatibility has been taken advantage of. When new Blue Line cars were delivered from Siemens Transportation in 2007, they were tested on the Orange Line after hours, before acceptance for revenue service on the Blue Line. The Red Line is incompatible with the Orange and Blue Lines, as its cars are wider and use yet another platform height; having a train on the Blue or Orange lines run on that line would result in a relatively wide gap between the platform edge and the train. The Green Line is incompatible with the other subway lines due to having a different propulsion system.[12]
| Line | Length | Width | Platform Ht. | Power |
|---|---|---|---|---|
| Red | 69.5' | 120" | 49" | Third rail |
| Orange | 65' | 111" | 45" | Third rail |
| Blue | 48' | 111" | 41.5" | Third rail, Overhead |
| Green | 72 | 104" | Low | Overhead |
There are no direct track connections between lines, except between the Red Line and Ashmont–Mattapan High Speed Line, but all except the Blue Line have little-used connections to the national rail network, which have been used for deliveries of railcars and supplies.[13]
Fares
As of 1 July 2019, MBTA fares are based on the trip type. A one-way ticket costs $2.40 whether loaded onto a reusable, fare-loadable CharlieCard, purchased as a single-use paper ticket, or paid in cash onboard the Green Line. The monthly LinkPass (which includes unlimited travel on rapid transit and bus) costs $90 per month. Daily and weekly passes are available at $12.75 and $22.50, respectively, and discounts are provided to seniors and high school students. Children up to 11 years old ride free when accompanied by an adult; limit 3.[14]

The Everett-Forest Hills Main Line Elevated was renamed the Orange Line on Aug. 25, 1965. The name comes from a section of Washington Street between Essex and Dover streets that had the name Orange Street until the early 19th century, said Clarke. However, according to architecture firm Cambridge Seven Associates, the Orange Line's color was a design choice after the yellow color option did not test well.

I remember sitting in my Cambridge office preparing for a meeting with the MBTA in which I would be proposing colored lines. I had markers in front of me and I chose red for the line that went to Harvard since it's a well-known institution whose main color is crimson. One line went up the North Shore of Boston up to the coastal areas, so it seemed obvious to call that the Blue Line. The line that serves Olmsted's Emerald Necklace was an obvious choice for green. And then the fourth line ended up being orange for no particular reason beyond color balance.
