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 or Subway system.[1]
The colored rail trunk lines consist of 3 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; no route operates entirely underground. The four branches of the Silver Line bus are also shown as part of the rapid transit system. Two 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 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 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.[3] 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.[citation needed]
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" segments in Boston 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 trolley 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 Ashmont or Braintree.
The trolley lines include 4 Green line branches which terminate in Brighton, Brookline, Newton, and Roxbury, and the Mattapan High Speed Line. lver Line Two branches of the Silver line, the SL1 and SL2, operate underground as part of the subway system[dubious – discuss], with direct transfers at South Station. These two lines use the higher subway fare, while SL4 and SL5 follow bus fare rules.

Layout
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, 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
The colors were assigned on August 26, 1965 in conjunction with design standards developed by Cambridge Seven Associates,[5] and have served as the primary identifier for the lines since the 1964 reorganization of the MTA into the MBTA. The Orange Line is so named because it used to run along Orange Street (now lower Washington Street); the Green Line because it runs adjacent to parts of the Emerald Necklace park system; the Blue Line because it runs under Boston Harbor; and the Red Line because its northernmost station used to be at Harvard University, whose school color is crimson.[6][dubious – discuss]
Stations
The MBTA rapid transit system consists of 133 stations, with another 7 in construction as part of the GLX project in Somerville.
Rolling stock
The four transit lines all use standard rail gauge, but are otherwise incompatible; trains of one line would have to be modified to run on another. Orange and Blue Line trains are similar enough that modification of some Blue Line trains for operation on the Orange Line was considered, although ultimately rejected for cost reasons. Also, some of the new Blue Line cars from Siemens Transportation were tested on the Orange Line after hours, before acceptance for revenue service on the Blue Line. 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.[7]
Fares
As of July 1, 2016, MBTA fares are based on the trip type. A one-way ticket or cash on board costs $2.75, or $2.25 if loaded onto a reusable CharlieCard. The monthly LinkPass (which includes unlimited travel on rapid transit and bus) costs $84.50 per month. Daily and weekly passes are available at $12.00 and $21.25, 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.[8]
