Trolleybuses in Greater Boston

The Boston-area trolleybus (or, as known locally, trackless trolley) system formed part of the public transportation network serving Greater Boston in the U.S. state of Massachusetts. It opened on April 11, 1936,^[2][3] with a large network operating for the next quarter-century. Measured by fleet size, the Boston-area system was the second-largest trolleybus system in the United States at its peak (end of 1952), with only the Chicago system having more trolleybuses than Boston's 463 (with the Atlanta system being close behind Boston, with 453).^[2][4] After 1963, the only remaining portion was a four-route cluster operating from the Harvard bus tunnel at Harvard station, running through Cambridge, Belmont, and Watertown. The Massachusetts Bay Transportation Authority took over the routes in 1964.

The system was expanded by the Silver Line (Waterfront), a 2004-opened bus rapid transit network using dual-mode buses which ran as trolleybuses in a tunnel in the Seaport District of Boston before switching to diesel power to serve other destinations. The Harvard lines were converted to diesel hybrid buses in 2022, followed by the Silver Line in 2023.

The first trackless trolley line in the Boston transit system was opened by the Boston Elevated Railway (BERy) on April 11, 1936. Replacing a streetcar line over the same route, it was a crosstown line (later numbered 77, and today served by the 69 bus) running from Harvard station east to Lechmere station. (Substitution of buses for streetcars on the route had been proposed as early as 1930.)^[5] Additional lines were opened in 1937, and by 1942, the system had 14 lines, of which 10 were former streetcar lines and four were former motor bus lines.^[3] In 1947, the BERy was succeeded by the public Metropolitan Transit Authority (MTA) as the operator of Boston's urban transit system,^[3] and in 1964, the MTA was replaced by the Massachusetts Bay Transportation Authority (MBTA), which remains the system's operator today.^[6]

The BERy was owned by private investors, but came under public control from 1918. It served 13 municipalities of Greater Boston, including Boston proper. The MTA's service area was limited to these municipalities (with the addition of Revere). Following a change of management, the MTA began replacing trolleybuses with motorbuses, starting in 1958. Only four trolleybus lines remained after 1963, all based in Cambridge. Four decades later, the MTA's successor, the MBTA, built the Silver Line (Waterfront), and that line's opening in late 2004 reintroduced trolleybus service in Boston proper.

At the trolleybus system's peak, the maximum number of trolleybus routes in operation was 37, with most routes running in the near north suburbs of Boston. In addition, there were the disconnected Dorchester and Arborway networks.

Prior to the opening of the Silver Line, a total of 43 trolleybus lines had historically existed, but not all concurrently,^[6] making the all-time total 44 (counting the Silver Line trunk as one route) as of 2022^[update].

Harvard-based routes

History

A Flyer trolleybus in the upper level of the Harvard bus tunnel in 2003

What became the Harvard-based trolleybus system began as branches of the Cambridge Railroad, a horsecar street railway that opened in 1856. Lines from Harvard Square to Mount Auburn via Brattle Street and Porter Square opened soon after the Harvard Square–Bowdoin Square route.^[11][12] The connecting Watertown Horse Railroad opened on April 27, 1857.^[13] The Porter Square branch was extended to the border of West Cambridge (now Arlington); there it met the West Cambridge Horse Railroad, which opened on June 13, 1859.^[12][14] In 1880, the Watertown line was extended south on Galen Street to Nonantum Square.^[15]

The Harvard–Arlington line was electrified on July 1, 1889 – one of the first lines converted by the West End Street Railway.^[16] Electric service between Watertown and Mount Auburn began on December 12, 1893; the line was double-tracked later in the decade.^[17][18] Residents of Brattle Street objected to the construction of electric lines; in October 1893, the Board of Railway Commissioners denied the West End permission to run electric streetcars on Brattle Street.^[11][19][20] That November, a compromise was worked out where the West End would instead build on Mount Auburn Street (which had been considered in 1891^[21]); a parallel line on Concord Avenue and Huron Avenue (ending at Aberdeen Avenue and Mount Auburn Street) would be opened within eight months, and the Brattle Street horsecar tracks removed in the same time frame.^[22] The Mount Auburn line opened in April or May 1894, with the Concord/Huron line opening later in the year.^[23][24][25]

A branch from Mount Auburn Street to Waverley Square in Belmont opened on October 1, 1898, despite Watertown's opposition earlier than year to widening Belmont Street.^[26][27] A branch to Belmont Center opened on June 30, 1906; it was replaced by buses in August 1928 and was never a trackless trolley route.^[28][29][30]

On April 1, 1938, trackless trolleys replaced streetcars on the Harvard–Aberdeen Avenue line (72). In 1955 the Harvard–Arlington Heights line was converted from streetcars to diesel buses, but streetcars continued to provide short-turn service between Harvard and North Cambridge.^[9] Starting in 1957, trackless trolleys provided short-turn service from Harvard to Benton Square on the route to Waverley.^[31] The Harvard–Watertown Square (71), Harvard–Waverley (73), and Harvard–North Cambridge (82, renumbered 77A c. 1967^[10]) lines were all converted from streetcars to trackless trolleys on September 6, 1958.^[9]: 220

These four Harvard-based trackless trolley routes remained long after the rest of the bus system had converted to diesel and existed, in part, because of a desire to limit the number of diesel buses in the Harvard bus tunnel. Inside the portals, the tunnel splits into two one-way tunnels, upper and lower. The tunnel for eastbound-northbound vehicles is placed on top of the tunnel for southbound-westbound vehicles.^[32] The tunnels first opened for streetcars in 1912, and trolleybuses began using them in 1938.^[6] Streetcar service using the tunnel was abandoned in 1958. In a six-year project lasting from 1979 to 1985 (coinciding with the reconstruction of Harvard station during the Northwest Extension of the MBTA Red Line), the tunnel was closed for an extensive rebuilding, which included new platforms and a new northern portal ramp.^[6] (The preservation of these lines has also been attributed to the environmentalist movement of the 1970s.^[33])

In January 2005 most route 77A (Harvard–North Cambridge) service was eliminated; the only remaining trips were pull-ins and pull-outs to take 71 and 73 buses to or from the carhouse.^[10] In March 2013, route 72 trackless trolleys were replaced with diesel buses to permit roadwork on Huron Avenue and reconstruction of the Conductor's Building in Bennett Alley.^[10] It was planned that route 72 would return to electric operation when construction was complete, but service was reduced to peak-only in December 2019 (in conjunction with improvements to routes 74 and 75 which also run on Concord Avenue),^[34] and all route 72 service was suspended indefinitely in December 2020.^[35][36]

In 2021 the MBTA announced plans to renovate the North Cambridge Carhouse facility by 2023 to accommodate battery electric buses, eliminating trolleybus operations on all Harvard-based routes.^[37][38] This included shifting the North Cambridge routes to another, unelectrified garage in 2022 to permit rebuilding of North Cambridge to begin unimpeded by active operations.^[39] Trolleybus service on the last two surviving routes, 71 and 73, ended on March 12, 2022.^[40][41] Multiple utility and road-rebuilding projects beginning in early 2022 led MBTA to decide to substitute diesel hybrid buses for trolleybuses at that time.^[42]

Vehicles

1976 Flyer E800 trolleybus at Cambridge Common, followed by the newer Neoplan AN-440LF trolleybus

In the lower/westbound tunnel, the loading platforms are located on the left side of the roadway, and for this reason the trolleybuses serving this station were equipped with left-side doors, in addition to the normal righthand doors, to avoid the need to board passengers from doors facing the wall rather than the platform. Diesel buses serving the tunnel are not equipped with left-side doors, and passengers boarding or deboarding at the westbound stop must cross the roadway to reach the buses' doors.^[32] In 2004, the MBTA began receiving a fleet of new trolleybuses from Neoplan USA, to replace Flyer E800 trolleybuses dating from 1976. The newer vehicles were low-floor vehicles and met Americans with Disabilities Act standards (see MBTA accessibility).

Operations

The vehicles for Harvard-based routes were all stored overnight and maintained at the North Cambridge Carhouse, the northern terminus of the 77A route. Trackless trolleys did not run on Sundays; instead, diesel buses covered the routes.^[31]: 18 This was the case since 1963.^[43]

To expedite passenger boarding through a left-side door in the southbound Harvard bus tunnel, the 71 and 73 trackless trolley routes allowed free entry for outbound trips, collecting fare upon later passenger exit from the vehicle.

Silver Line

Main article: Silver Line (MBTA)

Dual-mode bus in electric mode at the top of the Silver Line tunnel ramp

A Silver Line dual-mode bus changes from electric to diesel mode at Silver Line Way

The Silver Line is split into two sections; the diesel-powered Washington Street section runs entirely on the surface, but the Waterfront section runs through a dedicated tunnel under the South Boston Waterfront, in which diesel emissions would be problematic. Several routes branch out from the tunnel along routings where installation of overhead trolley wire would have been impractical, especially through the Ted Williams Tunnel (as overhead wires are expressly prohibited on interstate highways^{[citation needed]}), so the Waterfront section uses dual-mode buses. The vehicles ran as trolleybuses within the 1.3-mile-long (2.1 km) tunnel and for about 900 feet (270 m) on the surface, then changed to diesel power at the end of Silver Line Way, and reversed the transition when inbound.^[44] Motor buses are not permitted to operate inside the South Boston Waterfront tunnel due to insufficient ventilation. Four routes ran in the electrified Silver Line tunnel: SL1 to Logan Airport, SL2 to Design Center, SL3 to Chelsea, and a shuttle route which short turns at Silver Line Way.

Until February 2006, the Silver Line also used 12 of the then-new conventional-length Neoplan trackless trolleys until the entire articulated, dual-mode fleet could be placed into service; they were temporarily "wrapped" in the Silver Line's silver paint scheme, covering the standard MBTA yellow-and-white.^[43] Only three of the 32 dual-mode buses on order had been accepted for service by the time the Silver Line opened,^[45] but the number had increased to 28 by February 2006.^[43] In fall 2005 (five vehicles)^[46] and the first half of 2006, the 12 Neoplan trackless trolleys were transferred to the Harvard-based routes to replace the then-remaining Flyer trolleybuses operating out of North Cambridge Carhouse.^[47]

Following the testing of a small number of battery buses on the line starting in July 2019,^[48] MBTA placed an order in November 2020 for 45 articulated "extended-range" diesel hybrid buses to replace the 32 dual-mode buses used on the Silver Line.^[35] Those new hybrid buses began to enter service in January 2023, and over the next several months they gradually replaced the dual-mode buses.^[49] The last day of service for any dual-mode buses, and the last day of use of the overhead trolley wires, was June 30, 2023 (with the only bus in service on that date making its last trip shortly after midnight, in the first hour of July 1).^[1] This development marked the permanent closure of the Boston trolleybus system and was the first abandonment of a U.S. trolleybus system in more than 50 years—since the closure of the Chicago system in March 1973.^[1]

Fleet

Boston's first trolleybuses were built by Pullman-Standard in 1936. Boston Elevated continued to buy its trolleybuses almost exclusively from Pullman, and until 1950 Pullmans comprised the entire fleet with the exception of a small batch of five Twin Coach trolleybuses purchased in 1937.^[3][31] In 1952, Boston had more Pullman-built trolleybuses than any other city, with 438.^[31]: 7 Meanwhile, 25 ACF-Brill trolleybuses built in 1950 were the only other purchase of non-Pullman trolleybuses until 1976. With several route closures in 1964, the Twin Coaches and the oldest Pullmans were retired, leaving only Pullmans built in 1947–51 in service.

These were all replaced in 1976–77 by a fleet of 50 Flyer E800s (4000–4049),^[32] the first of which arrived in February 1976 and entered service in April.^[50] The last Pullman-Standard trolleybuses were retired in August 1977.^[51] The Flyers were, in turn, replaced by new trolleybuses over the period 2004–06. Regular use of Flyers ended in June 2006, but a small number remained active and used very sporadically until March 2007.^[52] The only subsequent – and the final – use occurred on December 21, 2007, when the last two active Flyers (4006 and 4016) entered service briefly after all-night sleet-cutting duty (scraping ice off of the overhead wires).^[52]

In its final years the network that served Cambridge and vicinity used a fleet of 28 40-foot (12 m) vehicles. The order for these was placed in December 2000, in a single contract with the vehicles for the Silver Line,^[53] but the first vehicle (4101) was not completed and delivered until 2003.^[54] Except for the first unit, these trolleybuses (numbered 4101–4128) were delivered in 2004 and were the first low-floor trolleybuses in North America.^[54][55] The first day of service for trolleybuses in this series was June 4, 2004.^[56]

The Silver Line fleet consisted of 32 60-foot (18 m) low-floor, articulated dual-mode buses (numbered 1101–1132). These were built by Neoplan USA and fitted with Škoda electrical equipment, and delivered in 2004–2005. Eight of the buses (1125–1132) were funded by Massport and came equipped with luggage racks for airport passengers (and fewer seats than the other buses, 38 instead of 47), for use on route SL1, which serves Logan International Airport.^[57] In January 2011, four more buses (1121–1124) were also equipped with luggage racks in place of some seats.^[58]
