MBTA bus

Buses at Arborway Yard in 1967

A number of horsecar lines were built in Boston and surrounding towns in the second half of the 19th century, beginning with the Cambridge Railroad in 1856. Several smaller companies were consolidated into the West End Street Railway in 1887. The West End began electrifying existing lines and constructing new streetcar lines; the last horsecar lines ended in 1900. The West End was purchased in 1897 by the Boston Elevated Railway (BERy), which had been created to build a rapid transit system in Boston. As that system was constructed in the first two decades of the 20th century, many streetcar lines were cut back from downtown Boston to rapid transit stations. Stations like Sullivan Square, Dudley Square, Forest Hills, Harvard, and Andrew were built as transfer stations with easy connections between subway and rapid transit.

Some small companies operated buses in Boston as early as the 1910s. BERy bus service began on February 23, 1922, when buses replaced the North Beacon Street streetcar line.[4] Initial bus routes largely replaced lightly-used streetcar lines or expanded service to new areas. The BERy also attempted in the 1920s to make the Tremont Street streetcar subway operate more like a rapid transit line, using trains of streetcars entering the subway from a small number of feeder lines, rather than single streetcars from numerous surface lines.[5] The Harvard–Lechmere streetcar line was converted to trackless trolley (trolleybus) on April 11, 1936 – the first route in what would become an extensive trackless trolley system.[6]

As increased automobile usage reduced ridership and increased congestion, the BERy and its 1947 replacement Metropolitan Transit Authority (MTA) continued to convert streetcar lines to bus and trolleybus. Most trolleybus lines were replaced by buses in the late 1940s to early 1960s, as buses offered increased flexibility and no need to maintain overhead lines. When the Massachusetts Bay Transportation Authority (MBTA) replaced the MTA in 1964, all surface lines were operated by buses except six streetcar lines (the five Green Line branches plus the Mattapan Line) and four trolleybus lines.[7] The MBTA rebranded many elements of Boston's public transportation network in its first decade. After being found unsuitable in 1965 for the Orange Line because it did not show up well on maps, yellow was chosen for the color of bus operations on January 8, 1972.[8][9]

The MBTA had primarily been formed to subsidize the suburban commuter rail network. However, the agency also took over unprofitable suburban bus operations – much of which was former streetcar lines – from several private companies. The MBTA took over the Eastern Massachusetts Street Railway in 1968, inheriting large networks based in Lynn and Quincy plus several lines in Norwood and Melrose. (Networks serving Lowell, Lawrence, and Brockton outside the MBTA district were briefly operated by the MBTA. They were transferred to new public agencies: the LRTA in Lowell in 1976, a predecessor of the MVRTA in Lawrence in 1968, and a predecessor of the BAT in Brockton in 1969.) The MBTA began subsidizing Middlesex and Boston Street Railway service based in Newton and Waltham in 1964, and took over the remaining routes in 1972. Five former Service Bus Lines routes in northeast suburbs were taken over in 1975, and a single Brush Hill Transportation line in Milton was taken over in 1980.[7]

The geographic scope of the MBTA bus network has remained relatively constant since these additions, though many services have been created, discontinued, and modified during the MBTA era. The openings of new sections of the Red Line (1971, 1980, 1984–85) and the Orange Line (1975–77, 1987) have resulted in significant changes as routes were modified to serve new transfer stations.[7] Three limited-stop crosstown routes were created in 1994 as a prelude to the Urban Ring Project, a never-implemented circumferential bus rapid transit (BRT) corridor. Silver Line BRT service began in 2002 with conversion of existing bus service on Washington Street, and was expanded in 2004–05 with new routes serving the Waterfront Tunnel in the Seaport District. The latter used dual-mode buses that operated as trolleybuses in the Waterfront Tunnel and as diesel buses on the surface. A second Silver Line service using the Washington Street corridor was added in 2009, and service from the Waterfront Tunnel to Chelsea began in 2018 with a new surface busway in Chelsea.[7]

The BERy and MTA operated overnight Owl service until 1960. From September 2001 to June 2005, the MBTA operated bus service on 17 routes (7 normal bus routes and 10 routes replicating subway lines) until 2:30am on Friday and Saturday nights. Similar service on the key routes was operated from March 2013 to March 2014.[7] In 2017, the MBTA Board rejected a proposal to run all-night service on several routes with pulsed connections at a central hub.[10]

In 2018, the MBTA began planning for the Bus Network Redesign, a reworking of the entire bus network.[11] A draft plan was released in May 2022, with a revised plan in November 2022.[12][13] That plan was approved in December 2022. It increases overall service by 25%, with a doubling of the number of routes with high-frequency service. As of October 2023, the first changes are planned to be made in December 2024, with additional changes through 2028.[14]

In 2022, the MBTA started cutting bus service due to a driver shortage resulting from a long-term retirement trend accelerated by the COVID-19 pandemic in Massachusetts. Despite paying for training to get a commercial driver's license and offering a $4,500 signing bonus, it ended the year short about 350 drivers, plus about 400 more needed to increase service to implement a proposed bus network redesign. Experts said the shortage was caused by the failure to raise the starting hourly wage, and offer new hires full-time work instead of forcing all of them to start part-time. Drivers were also unhappy about lack of access to bathrooms and "split shifts" with unpaid time between morning and evening rush hour that was too short to go home.[15] The MBTA began hiring operators for full-time work in 2023.[16]

This is the current bus roster for the MBTA as of October 2023. All buses are 102 inches (260 cm) wide; most buses are 40-foot (12 m) length, while 117 are 60-foot (18 m) articulated buses.[1] An additional 80 New Flyer 40-foot battery-electric buses were ordered in July 2023, with the first ten to be delivered in 2024 and the remainder in 2025–26. Thirty-two of those buses will have left-side doors for use in the Harvard bus tunnel.[17][18]

MBTA buses are operated out of eight facilities.[1]

Most local bus routes in Massachusetts outside the immediate MBTA operating area are operated by the state's other regional transit authorities (RTAs). However, some routes that connect with MBTA bus or subway service are operated by outside private contractors with partial subsidy by the MBTA. [27]

Five routes – the 710, 712/713, 714, and 716 – are numbered like other MBTA buses. The five routes are primarily commuter routes which connect with other MBTA services at their inbound terminals. They were taken over from various private operators (Hudson Bus Lines for the 710 and 716, Rapid Transit Inc. for the 712/713, and Nantasket Transportation for the 714).[7] The 712 and 713 use MBTA-provided buses and accept Charliecards; the other routes do not.

Four suburban municipalities contract with outside operators for local circulator routes, most with partial MBTA subsidy. Bedford and Beverly run single routes, Burlington runs five routes, and Lexington runs six.[7] Most are run by private operators, except for the Beverly Shuttle, which is part of the Cape Ann Transportation Authority system. Additionally, a nonprofit shuttle is run in Boston's Mission Hill neighborhood.[7] Those routes appear on MBTA system maps and connect with MBTA services at designated transfer points, but are numbered separately and do not accept MBTA passes.

Several sections of dedicated right-of-way for MBTA buses have been opened in the 21st century. Two sections of the Silver Line have off-street busways: The 2004-opened 1.2-mile (1.9 km) South Boston Piers Transitway tunnel in the Seaport (used by the SL1, SL2, SL3, and SLW), and a 2018-opened 1.1-mile (1.8 km) surface busway in Chelsea used by the SL3. A direct ramp to the Ted Williams Tunnel is proposed for use by the SL1 and SL3.
