The '''San Francisco [[trolleybus]] system''' forms part of the [[public transportation]] network serving [[San Francisco]], in the [[States of the United States|state]] of [[California]], [[United States]].  Opened on October 6, 1935,<ref name="muni history" /> it presently comprises 15 lines, and is operated by the [[San Francisco Municipal Railway]], commonly known as ''Muni'' (or the Muni), with around 300 trolleybuses.  In San Francisco, these vehicles are also known as "trolley coaches", a term that was the most common name for trolleybuses in the United States in the middle decades of the 20th century.

The Muni trolley bus system is complementary to the city-owned [[List of San Francisco Municipal Railway lines|Muni bus services]], [[Muni Metro]] and [[San Francisco cable car system|cable car system]] and the rail-bound regional [[Caltrain]] and [[Bay Area Rapid Transit]] systems. In addition, it shares some of its [[overhead wires]] with the [[F Market & Wharves]] streetcar line.

One of only five such [[List of trolleybus systems in the United States|systems currently operating in the U.S.]],<ref name="janes2013"/> the Muni trolley bus system is the second-largest such system in the [[Western Hemisphere]], after that of [[Servicio de Transportes Eléctricos|Mexico City]].

Long a hub of [[streetcar]] development, San Francisco already had much of the overhead wire infrastructure necessary to deploy trolleybus service on existing city streets. A city ordinance requiring streetcars to use two operators also served to encourage trolleybus deployment.<ref name=Callwell99/>{{rp|40}} In April 1934, Col. Jno H. Skeggs of the State Highway Department urged the conversion of the No. 33 Line streetcar to "trackless trolley",<ref name=Trib-340419>{{cite news |url=https://cdnc.ucr.edu/?a=d&d=OT19340419.1.12 |title=Trackless Trolley Line Urged in S.

On September 7, 1941, Muni introduced its first trolleybus line to compete with MSRy, the '''R-Howard''' line, using vehicles built by the St. Louis Car Company.<ref name=Callwell99/>{{rp|42}} R-Howard was built on the original route of the sparsely ridden No. 35 streetcar line; MSRy's franchise to operate the No. 35 had expired at the end of the 1930s.<ref name=RUready>{{cite web |url=https://www.streetcar.org/r-you-ready-munis-first-trolley-bus-line-runs-again-sept-24-25/ |title='R' You Ready?

Although the overhead wires are still present along Howard, they are not used in revenue service.<ref name=RUready /> The present-day 14-Mission trolleybus route runs along Mission, parallel to the original R-Howard route on Howard.<ref>{{cite web |url=https://www.sfmta.com/routes/14-mission |title=14 Mission |publisher=San Francisco Municipal Transportation Agency |accessdate=4 February 2019|date=2012-12-19 }}</ref> By 1944, the MSRy was in financial difficulties. Thus, at 5&nbsp;am on September 29, 1944, Muni acquired its commercial competitor. Along with the routes and equipment, Muni adopted its competitor's more expensive seven-cent fare (${{inflation|US|.07|1941|r=2}} adjusted for inflation).<ref name="muni history" /> At the time, the R-Howard line used 9 trolleybuses over a {{convert|6.8|mi}} route (round-trip).<ref name=Callwell99/>{{rp|44}}

[[File:Muni trolleybus wires at Haight.jpg|thumb|left|Muni trolleybus wires at McAllister & Divisadero streets.]]
The city attorney's office had ruled that using trolleybuses instead of streetcars was not abandonment of service; this opinion would eventually be overturned in 1959,<ref name=Callwell99/>{{rp|46}} but not before Muni followed national trends in replacing most of its streetcar rail lines with trolleybus service in the 1940s and 1950s. The E-Union line was the first to be replaced with trolleybus service, which combined the route with R-Howard as the E-Union-Howard. Trolleybus operation on the new E line commenced on June 9, 1947; it was redesignated in 1949 and survives as the 41-Union.<ref name=Callwell99/>{{rp|45}} 8-Market was converted to trolleybus service in 1948.<ref name=Callwell99/>{{rp|46}} The deployment of new "trackless trolleys" was greatly expanded on July 3, 1949, when Muni rolled out trolleybus service to replace five former MSRy lines,<ref name=Callwell99/>{{rp|46}} including the 21-Hayes and 5-McAllister streetcar lines.<ref name=SFC-180312>{{cite news |url=https://www.sfgate.com/bayarea/article/As-wires-crossed-in-1949-Muni-championed-12703913.php?t=09d057cd65 |title=As wires crossed in 1949, Muni championed electric bus future |author=Hartlaub, Peter |date=March 12, 2018 |newspaper=San Francisco Chronicle |accessdate=30 January 2019}}</ref> In total, [[List of defunct San Francisco Municipal Railway lines#Defunct streetcar routes|fourteen streetcar lines]] were converted to trolleybus service by 1951.<ref name="muni history"/> With the closure of the B-Geary line on December 29, 1956,<ref name=Callwell99/>{{rp|48}} only five lines with dedicated rights-of-way (including those running through the [[Twin Peaks Tunnel|Twin Peaks]] and [[Sunset Tunnel|Sunset]] tunnels) continued as rail-based streetcar lines. Those five lines ran 1940s-era [[PCC streetcar]]s through the 1970s and were subsequently converted to the [[Muni Metro]] light rail system using [[Boeing-Vertol]] [[US Standard Light Rail Vehicle|SLRV]]s.<ref name=Callwell99/>{{rp|48–49;56}}

===Grade===
While many municipalities further converted their trolleybus systems to diesel buses during the middle of the 20th century, San Francisco maintained trolleybuses due to their ability to climb the city's notably steep [[Grade (slope)|grade]]s and because electricity was available at extremely low cost from the city-owned [[O'Shaughnessy Dam (California)|O'Shaughnessy Dam]].<ref name=Callwell99/>{{rp|46}}&nbsp;<ref>{{People's Railway|page=176}}</ref> Muni has stated that it is impossible for some lines to be replaced by regular buses.<ref>{{cite news |url=https://www.sfgate.com/bayarea/article/Muni-trolley-wire-visual-pollution-electrifies-5056671.php |title=Muni trolley wire 'visual pollution' electrifies debate |author=Wildermuth, John |date=May 19, 2014 |newspaper=San Francisco Chronicle |accessdate=6 February 2019}}</ref> The system includes the single steepest known grade on any existing trolley bus line in the world,<ref name=perles-tours/><ref name=tm165/><ref name="tm261"/><ref name="tm313"/> specifically 22.8% in the block of Noe Street between Cesar Chavez Street and 26th Street on route 24-Divisadero,<ref name=perles-tours/><ref name="tm261"/><ref>{{cite web |title=General Information About Transit |url=http://www.sfmta.com/cms/rhomemu/genmuinfo.htm |archiveurl=https://web.archive.org/web/20130128233714/http://www.sfmta.com/cms/rhomemu/genmuinfo.htm |archivedate=January 28, 2013 |date=2012 |publisher=San Francisco MTA |accessdate=July 24, 2016}}</ref> and several other sections of Muni trolley bus routes are among the world's steepest.<ref name="tm259"/>

On December 16, 1981, the 55-Sacramento line was converted from diesel motor coach service to the 1-California trolleybus specifically to power the westward climb on Sacramento up [[Nob Hill]].<ref name="muni history"/> Before dieselization, the line had been operated using cable cars. At the time, Muni was also facing a severe shortage of available diesel motor coaches due to age and deferred maintenance, which would lead to the conversion of the 45-Greenwich diesel bus service to the 45-Union-Van Ness trolleybus in 1982 as a temporary experiment later made permanent.<ref name=Callwell99/>{{rp|59–60}} In 1993, 31-Balboa was partially converted to trolleybus service, with full implementation delayed until 1994, when accessible Flyer E60 trolleybuses became available.<ref name=Callwell99/>{{rp|74–75;78}} Coming full circle, at the end of 1995 the 8-Market trolleybus line was replaced by the [[F-Market & Wharves]] streetcar line using refurbished PCCs. The overwhelming popularity of the new F line allowed Muni to reduce the frequency of and then discontinue 8-Market.<ref name=Callwell99/>{{rp|81}}

Approximately {{frac|3}} of the daily riders on Muni are carried on trolleybuses;<ref name=SFE-960216/> in 2010, that was 227,000 passenger boardings per weekday.<ref name=2010-FleetMgmt/>{{rp|5}}

==Fleet==
[[File:Ferry Building with Muni trolleybus, 1953.jpg|thumb|left|upright|Muni Marmon-Herrington trolleybus in front of the [[Ferry Building (San Francisco)|Ferry Building]] on [[Market Street (San Francisco)|Market]] (1953)]]
Since the start of service in 1935 (on the Market Street Railway system), the San Francisco trolleybus system fleet has included vehicles built by many different manufacturers, including the [[J. G. Brill Company]], the [[St. Louis Car Company]], [[Marmon-Herrington]], [[Twin Coach]], [[New Flyer|Flyer Industries]] (now New Flyer), and [[Electric Transit, Inc.|Electric Transit]].<ref name="Inside Muni"/>

===Early fleet (Brill, St. Louis)===
Market Street Railway was the first transit organization in San Francisco to run trackless trolleys, using nine coaches built by Brill in 1935 for the 33 line, numbered 51–59. Each Brill was {{convert|33|ft|abbr=on}} long and seated 37; approximately half used traction motors from General Electric (GE) and the other half used Westinghouse (WH) motors. Shortly after Muni assumed MSRy's operations in 1944, the Brill coaches were replaced by newer trolleybuses built for Muni and transferred to supplemental rush hour service by 1946. All of the Brill coaches were scrapped by 1954.<ref name=IM-Brill/>

[[File:Trolley -506 (31761035891).jpg|thumb|right|The oldest remaining trolleybus in San Francisco is the St. Louis-built No. 506, photographed in 2012.]]
Muni commissioned its first trolleybuses in 1941 from the St. Louis Car Company; these were 40-seat coaches. Like the earlier Brills built for MSRy, the first set of nine St. Louis coaches used motors from GE and Westinghouse. These coaches, numbered 501–509, went into service on the R-Howard Line. A second order in 1947 for 16 slightly larger coaches completed the first fleet of 25 coaches for Muni.<ref name=IM-StL1/>

===Replacing streetcars (Marmon, Twin Coach, St. Louis)===
The Muni trackless trolley fleet was expanded starting in 1947 as streetcar service was being replaced. Muni primarily purchased trolleybuses from Marmon-Harrington in three different sizes: the "Baby Marmons" in 1947 (Model TC40, numbered 526–549, 40 seats), followed by "Medium Marmons" in 1949 (Model TC44, numbered 550–569 and 660–739, 44 seats), and finally "Large Marmons" in 1950 (Model TC48, numbered 740–849, 48 seats).The Baby Marmons were relegated to supplemental service by 1954 and retired by 1961; most were scrapped, with few exceptions, by 1969.<ref name=IM-Marmon/>

[[File:Muni 5300 and 776 at Heritage Weekend, September 2017.JPG|thumb|left|Flyer no. 5300 and its predecessor, Marmon-built no. 776 (originally 786), photographed at Heritage Weekend in 2017]]
In addition, Muni ordered 90 trolleybuses from Twin Coach comparable to the Medium Marmons in 1949 (Model 44TTW, numbered 570–659, 44 seats).<ref name=IM-Twin/> The final expansion of the trolleybus fleet in the 1950s was accomplished by purchasing 40 48-seat coaches from the St. Louis Car Company in the early 1950s.<ref name=IM-StL2/> The mixed fleet of Medium and Large Marmon, Twin Coach, and St. Louis trolleybuses would serve Muni throughout the 1960s and well into the 1970s; by the time Muni was ready to replace its trolleybuses, however, no American manufacturer was willing to build a new trolleybus. Muni turned to [[New Flyer Industries|Flyer Industries]], a Canadian manufacturer who was still building trolleybuses for their domestic market.<ref name=IM-Flyer/>

===Flyer and New Flyer===
[[File:Ad-free Muni Flyer E800 trolley bus in 1983, on Mariposa St by Potrero Garage.jpg|thumb|right|A 47 Van Ness Muni Flyer E800 trolley bus exiting service, 1983]]
By 1977, with the delivery of more than 300 [[Flyer New Look bus|Flyer E800 trolleybuses]], Muni was able to retire its existing fleet of trolleybuses; the newest of those (outside the Flyers) was by then more than 25 years old. A significant portion of the legacy Marmon/St. Louis fleet was sold to Mexico City.<ref name="Inside Muni"/>

As the fleet of Flyer trolleybuses aged, reliability declined. In 1991, the fleet of Flyer E800 trolleybuses traveled a mean distance of {{convert|2000|mi|abbr=on}} between failures (MDBF). By 1995, the MDBF had fallen to just {{convert|600|mi|abbr=on}}, and each breakdown was taking an average of 4{{frac|4}} days to fix, often compounded by the unavailability of parts for the E800s, which were nearly 20 years old at that point.<ref name=SFE-960216>{{cite news |url=https://www.sfgate.com/news/article/Muni-s-trolleys-a-constant-problem-3151240.php |title=Muni's trolleys a constant problem |author=Lewis, Gregory |date=February 16, 1996 |newspaper=San Francisco Examiner |accessdate=6 February 2019}}</ref> In addition, a number of incidents where poles had detached from the wires and subsequently struck pedestrians and vehicles gained publicity at the time.<ref>{{cite news |url=https://www.sfgate.com/news/article/Ominous-pattern-of-trolley-accidents-3057671.php |title=Ominous pattern of trolley accidents |author=Finnie, Chuck |date=November 25, 1998 |newspaper=San Francisco Examiner |accessdate=6 February 2019}}</ref>

In 1993, Muni procured a fleet of 60 [[New Flyer High Floor|New Flyer E60]]s, that agency's first use of articulated trolleybuses.<ref name=2010-FleetMgmt/><ref>{{cite journal |title=San Francisco Municipal Railway Articulated Trolley Coach Procurement |author=James, Robert F. |date=1993 |volume=102 |journal=Journal of Commercial Vehicles |pages=647–660 |publisher=SAE International|jstor = 44722970}}</ref> Muni was the only customer for the E60 trolleybus variant of the New Flyer Galaxy; a prototype was built in 1992 and numbered 7000 for evaluation before the larger purchase was completed.<ref>''Trolleybus Magazine'' No. 193 (January–February 1994). National Trolleybus Association (UK). {{ISSN|0266-7452}}.</ref> The New Flyer E60 fleet subsequently were blamed for increasing the fleet accident rate. By 1996, the fleet average was 12.5 accidents per {{convert|100000|mi|abbr=on}} traveled; in comparison, the E60 rate was 26 accidents over the same distance.

===Electric Transit, Inc.===
The [[Electric Transit, Inc.]] (ETI) trolleybuses were delivered between 2001 and 2003, and came in two different models: 240 40-foot units (model 14TrSF) and 33 articulated 60-foot units (model 15TrSF), specially derived from the [[Škoda Works|Škoda]] [[Škoda 14Tr|14Tr]] and [[Škoda 15Tr|15Tr]], respectively, for use on the Muni system. The suffix SF in the two ETI model numbers stands for San Francisco.<ref name=SFC-010524 /> During testing, the new ETI trolleybuses were compared to a "luxury car" by one driver, and touted features included a new pneumatic system to raise and lower trolley poles and an on-board battery to allow off-wire operation for up to {{convert|2+1/2|mi|abbr=on}}.<ref>{{cite news |url=https://www.sfgate.com/green/article/On-New-Buses-Muni-Rides-Become-a-Glide-Slick-2961084.php |title=On New Buses, Muni Rides Become a Glide / Slick trolleys join an aging fleet |author=Epstein, Edward |date=January 23, 2001 |newspaper=San Francisco Chronicle |accessdate=30 January 2019}}</ref> However, the new ETI trolleybuses proved to be overweight during testing.<ref name=SFC-010524/>

===Retired fleet===
The trolleybus system's original fleet, owned and operated by the Market Street Railway when only MSRy was operating trolleybuses in San Francisco, were built by the [[J. G. Brill Company]]. MSRy merged with Muni in 1944, and in the years since then the trolleybus fleet has also included vehicles built by the [[St. Louis Car Company]], [[Marmon-Herrington]], [[Twin Coach]], and [[New Flyer|Flyer Industries]].<ref name="Inside Muni">{{Inside Muni|page=89}}</ref>

Several trolleybuses have been preserved after serving in San Francisco:
