Service and fares
The monorail takes approximately two minutes to travel between the Seattle Center and Westlake Center terminals, which are located apart.
Trains depart from each terminal approximately every 10 minutes, with a single train running continuously. The service has two seasonal schedules, with trains in the autumn and winter (September to May) operating for 13–14 hours per day from Monday to Saturday, ending at 11:00 p.m. on Fridays and Saturdays, and 12 hours on Sundays, ending at 9:00 p.m. The summer schedule is in use from May to September and has weekday trains operating for 16 hours and weekend trains for 15 hours, with service ending at 11:00 p.m. every day. Monorail service is typically reduced on

, but never proceeded beyond the early stages of construction.
Another plan from the Universal Elevated Railway Company in 1918 envisioned an elevated monorail system that would run along
Westlake Avenue in Seattle (near the modern-day monorail terminal), replacing the private
streetcar network. After the streetcars were acquired by the city government in 1919, its lobbying for a monorail system ceased. Other plans for monorail systems were submitted to the Seattle city government in 1930 and 1955, the latter as part of the
Everett–Seattle–Tacoma Tollway (modern Interstate 5).

system, but would use no local transit funding.
The operating costs were expected to be paid through fare recovery, while other options were considered for capital funding, including Lockheed buying back the system after the world's fair. Lockheed entered into final negotiations with the city and exposition organizers in late 1959, but the transit commission lost interest in running the system after the world's fair was shortened to six months instead of the original eighteen. The system's uncertain financing, not including engineering costs incurred by Lockheed, remained a major concern for the city government as negotiations continued into January 1960.
Alwac International, which had previously estimated it would cost $3.5 million ($ in dollars) to install their Alweg monorail system, submitted a proposal in February 1960 to finance and build the project themselves at no cost to the city or exposition organizers. The firm would collect monorail fares and revenue from terminal
concessions, and a surcharge on fair tickets, and transfer the system to the city government if the full $3.5 million cost was repaid; in the event that the system did not recoup the investment, it would have been dismantled and removed. Lockheed responded by presenting a modified bid to the transit commission in March with a $1 million buyback option, but they were dropped in favor of a new round of bidding by Alwac and the French engineering firm
SAFEGE.
The Century 21 Steering Committee, serving as the exposition's main organizers, took over negotiations from the transit commission and signed a preliminary construction contract with Alwac on May 20, 1960. The monorail would run along 5th Avenue from the fairgrounds to the intersection of Pine Street and Westlake Avenue, which would be converted into a permanent

around the fairgrounds that would use a
suspended monorail, but they were dropped five months later after the bidding firms were unable to obtain financing.
Construction and preparations

In March 1961, the city's Board of Public Works approved the construction and street use permits for the monorail project, which Century 21, Alwac, and local contractor
Howard S. Wright Construction Company would undertake.
Wright was also named a financing partner for the monorail, contributing $375,000 ($ in dollars), and went on to build the Space Needle and
Seattle Center Coliseum. The construction permit included a requirement to remove the monorail within six months of the exposition's end, but Alwac had announced their intention to sell the Alweg system to the city government if they desired.
Alweg representatives unveiled the finalized design plans for the monorail later that month, while the two railcars were under construction at the

factory in West Germany. Century 21 broke ground on the monorail in a ceremony at the Westlake Mall on April 6, 1961, which was declared "Monorail Day" and featured the
Seattle Symphony Orchestra, a speech from Senator
Warren G. Magnuson, and free monorail tickets for the 500 people in attendance.
The wooden forms for the first of 80 monorail columns were laid in early May, and concrete pouring for the first column began on May 23 between Virginia and Lenora streets. A crane lifted the Virginia–Lenora columns, each weighing , onto a prepared concrete footing on June 15. Concrete pouring at the Westlake Mall terminal began in late June, with plans to build the station platforms over Pine Street. The monorail's precast concrete beams were assembled in Tacoma and trucked up to Seattle, with special permission from the
Washington State Highway Commission, and the first was installed on September 21 between Virginia and Stewart streets before advancing northwards. Column construction and girder installation took approximately eight months, with at least three lanes of traffic on 5th Avenue remaining open during most periods.
The steel girders at the Westlake Mall terminal were installed in October, followed by work on the Seattle Center terminal. By December 1961, most of the work on the tracks and 54 percent of work on the stations was complete, using of concrete and of steel. The last of the 138 guideway beams was hoisted and installed on January 9, 1962, near Denny Way to complete of track.

It made its first test run on April 10 and entered passenger service to replace the Blue Train temporarily before the beginning of the fair.
World's Fair
The monorail and Space Needle opened for a public preview on March 24, 1962, a month before the formal start of the Century 21 Exposition.
The inaugural monorail trip from the Westlake terminal carried 130 passengers who received commemorative medals, including the first riders, who had lined up several hours early.
An estimated 9,600 people rode the Blue Train on the monorail's first day, as did 24,000 over the preview weekend; service on the first day was suspended an hour earlier than scheduled because of a mechanical issue. Government officials and civic leaders officially christened the monorail on April 19. 179,000 passengers had boarded the trains during preview rides.
The Century 21 Exposition formally opened on April 21. Monorail fares during the fair were set at 50 cents one-way and 75 cents round-trip for adults and 35 cents one-way and 50 cents round-trip for children. Trains operated from 8:45 a.m. to 12:15 a.m. during the fair, taking 96 seconds to complete each trip. It carried 7.4 million passengers, about 90 percent of fair attendees, from April 21 to October 21.

. After the fair, the monorail operated with a reduced schedule, from 11:00 a.m. to 11:00 p.m. It was limited to one train over the winter months but averaged 1,200 daily passengers.
Fare box revenue generated from March 24 to September 17 fully covered the system's $4.2 million construction costs.
Alwac retained temporary ownership of the monorail system after the fair contracted to end on April 21, 1963. The city government was tasked with deciding whether the monorail should be demolished or sold to a public or private operator. Alwac was granted an extension of its existing street use permit to operate trains until October. Among the proposals considered was
Samuel J. LeFrak's plan to sell the system to

Flushing Meadows.
Alwac agreed to transfer the entire system, including the terminals and offices, to Century 21 Center, Inc., the operator of the fairgrounds, on June 3, 1963. The transfer came at no cost to Century 21 and allowed the monorail to remain in operation and included an extension of agreements with the city government and Seattle Transit System.
Ownership transfer and early years
Century 21 Center, Inc. ran into financial difficulties in late 1964, with $2 million in outstanding debt ($ in dollars), and began negotiating a takeover of all fairground operations by the city government, which already owned the Seattle Center property. As part of cost-saving measures, in October 1964 monorail ticket booths were eliminated and replaced with onboard attendants to take fares. Century 21 Center offered to sell the monorail to the city government for $600,000 ($ in dollars) as part of resolving its debts to the city and entering liquidation. Lacking an operating franchise, the corporation's liquidation trustees declined to take the

of the monorail system in December, and elected not to pay $200,000 for demolition. Negotiations continued for several months until the city government agreed in April to terminate its contracts with Century 21 and take over the fairground facilities. The monorail was transferred to the city government in May at a cost of $775,150 ($ in dollars), of which $414,128 ($ in dollars) was in the form of debt forgiveness.
The Seattle Center reopened for the summer season on June 1, 1965, with monorail fares lowered the following day to 25 cents for adults on a one-way trip to attract more patrons. The monorail's operating hours were extended to midnight on weekdays and Saturdays, and ridership in the first week of June doubled compared to the prior year. A group of property owners along the monorail route sued the city government in 1965 over the loss of views and other livability concerns stemming from the construction of the line. The city settled the lawsuit in 1968 at a cost of $776,249 ($ in dollars) for light and air easements on 82 parcels of property.
By the end of the 1960s, the monorail was averaging 10,000 passengers on weekdays and 14,000 on weekends during the peak summer season. The Seattle Transit System remained the contracted operator of the monorail until January 1, 1973, when the
Municipality of Metropolitan Seattle (Metro Transit) absorbed it to form a countywide transit system. The Seattle city government retained ownership of the monorail and awarded an operating contract to Metro Transit using funding from the Seattle Center department. Under Metro Transit, the monorail vehicles were renumbered 6201 and 6202 and given a new paint scheme in 1978, including the repainting of the red train to the green train.

Renovations and preservation

The southern terminus at Westlake Mall was originally a large station that straddled Pine Street along a section of Westlake Avenue that had been converted into a public plaza. The terminal had a sloped

between street level and the three elevated platforms
covered by a "scalloped" roof.
The plaza at Westlake Mall was sought as the location of an expanded downtown park, leading to a major renovation of the monorail terminal that began in January 1968 and completed in April 1968. Reduced monorail service continued while the terminal was shrunk with the removal of the outer platforms deemed unnecessary for post-fair demand and the replacement of the roof with a simpler design.
An emergency repair to the Westlake terminal was made in 1974 at a cost of $100,000 to replace metal shields that caught debris dropped by passengers on the platform.
A larger renovation was completed in 1988 to accommodate the downtown park, later named
Westlake Park, and the adjacent Westlake Center shopping mall and office complex.
The old terminal had been viewed as a "blight" on the area, which the city government sought for redevelopment as the center of Downtown Seattle's retail core beginning in the late 1960s.
The city considered several proposals for a shopping mall on the block on the north side of Pine Street in the 1970s, including hotels, movie theaters, a potential home for the
Seattle Art Museum

, and a new monorail terminal, but they were never realized.
After several years of litigation led by preservation activists, a new proposal from
The Rouse Company
The Rouse Company was a publicly traded shopping mall and community developer from 1956 until 2004, when GGP Inc., General Growth Properties (GGP) purchased the company. It was founded by Hunter Moss and James Rouse, James W. Rouse in 1939.

and a local developer was approved for construction in late 1985.
The new proposal included demolition of the monorail terminal to make way for a public park, while trains would terminate at a new station integrated into the shopping mall.
The relocation of the station was initially rejected in 1985 after engineers had discovered that the monorail tracks would require significant reconstruction to make the necessary turn into the station.
The city government proposed moving the columns onto the sidewalk on 5th Avenue instead and creating a gauntlet track, which would prevent the two trains from using the Westlake terminal at the same time. City councilmember

suggested using a retractable ramp to access the outer track. A temporary station would be used during mall construction to allow the monorail to continue operations. The monorail relocation project was estimated to cost $19 million ($ in dollars) with heavy reliance on a federal grant that was initially denied by the
Urban Mass Transportation Administration. The city considered several options, including running a single train, selling the system to Tacoma or demolishing the monorail entirely. In March 1986, it chose to keep the system and spend $2.7 million ($ in dollars) on the initial planning for the station overhaul and other renovations.
The federal government awarded a $5.6 million grant ($ in dollars) for the relocation project in late July, two months after construction began on a temporary terminal at 5th Avenue and Stewart Street. The old terminal at Westlake Mall closed permanently on September 1, 1986, and was demolished over the following two months. The temporary terminal and its platform opened on September 17, 1986, allowing monorail service to resume after a two-week suspension. It was built one block to the north at Stewart Street, next to the western track, and only served the blue train. The city council finalized a $7 million spending package ($ in dollars) in March 1987 to construct the permanent terminal, which would begin after work on Pine Street for the
Downtown Seattle Transit Tunnel advanced beyond the excavation stage.
The monorail project included improvements to the electrical systems and an expansion of the Seattle Center terminal, and work on the two trains. An extensive interior refurbishment was cut after the monorail project trended $1.7 million above budget ($ in dollars), and was later reduced to new paneling and floorboards. The Westlake Center shopping mall was opened to the public on October 20, 1988, with the new monorail terminal on the third floor used temporarily for one day before it closed for additional construction. Several days before the scheduled opening, engineers discovered the west track was too close to the platform and mall building, preventing its use. The discovery was made when a retractable boarding ramp at the terminal scratched the blue train during a test run; a hinge pin that failed to fold properly was identified as the cause for the misalignment. The ramp was fixed in November, but other technical glitches and extended safety testing delayed the opening of the new terminal station for four months. The new Westlake Center monorail terminal opened on February 25, 1989, alongside the return of the red train to service.
In 1994, a private company replaced Metro Transit (later King County Metro) and the Seattle Center as the monorail's operator, signing a ten-year contract with the city.
Metro had previously provided drivers and maintained the trains, while the Seattle Center employed ticket-takers and janitorial staff. Near the northern end of the line, the
Experience Music Project building (now the Museum of Pop Culture) was constructed over the monorail tracks from 1998 to 2000. The building was designed so that the tracks would pass through a valley at the center of the structure, with windows from the exhibit spaces facing the guideway. The monorail tracks and vehicles were declared a
historic landmark by the
Seattle Landmarks Preservation Board in April 2003 amid plans to demolish or replace the line as part of a
citywide monorail expansion. In July, the city council passed the landmark ordinance to provide protections to the two Alweg trains, but excluded the guideway to support its reuse for the expansion project.
The monorail began a long-term closure on March 16, 2020, due to decreased demand amid the

in the Seattle area. It reopened on May 28 with limited service and suspension of cash ticket sales, but was closed again over the weekend because of
protest activity in Downtown Seattle. Ridership in 2020 declined to 300,000 total, approximately 15 percent of the 2019 total.
Station expansions
The monorail was integrated into the regional fare system in October 2019 with the acceptance of mobile tickets and later the ORCA card.

), Seattle Monorail Services announced a renovation of the monorail terminals in February 2020 to handle larger crowds. The Westlake Center terminal was to be expanded to accommodate 6,000 people per hour with new fare gates and
ticket vending machines for ORCA cards and tickets. The NHL team would also fund free transit passes for attendees before and after games to reduce the number of car trips to the arena. A proposed second phase of the expansion program would have included a covered walkway and second entrance at the Westlake Center terminal with access from the Pine Street plaza and the transit tunnel station, but it was later abandoned.
NHL Seattle, the Kraken's ownership group, also announced that it would purchase a 50 percent stake in Seattle Monorail Services.
Construction on the remodeled stations began in April 2021 with the demolition of the station interiors,
which required a full suspension of monorail service for several weeks. Another month-long closure began in September to finish construction of the expanded Westlake terminal ahead of the first arena events in late October. The monorail reopened on October 11, 2021, with work completed on the renovated Westlake Center terminal, which is planned to handle up to 3,000 passengers per hour during events. The project was primarily funded by $6.6 million in private spending and a $5.5 million grant from the Federal Transit Administration. The Seattle Center terminal is planned to be renovated at a later date.
Since the opening of Climate Pledge Arena, monorail ridership has recovered to its pre-pandemic levels with more use outside of the peak tourist season.

Expansion proposals
The monorail has been the subject of several expansion proposals, with the primary goal of expanding it into a citywide rapid transit system. In 1961, businessman Ben B. Ehrlichman proposed that the then-unfinished monorail be extended north to
Alderwood Manor or
Mountlake Terrace and south towards

Renton. The initial system would have cost $60 million ($ in dollars), while a second line serving the
Eastside region would be built separately using a new
floating bridge.
Former Seattle Transit System manager Marmion D. Mills proposed his own monorail system in 1963 that would connect Seattle to Mountlake Terrace, Kent and the airport. Mills argued that a conventional subway system would be too expensive for Seattle and that the other alternative would be an expanded

systems for U.S. airports, envisioned an network with 41 stations and 700 monorail vehicles that would cost $500 million to build ($ in dollars). The PSCOG did not submit the proposal for further consideration.
The city government announced its own plan in 1970 to extend the monorail to a parking garage on
Mercer Street near the site of a
proposed stadium, but it was shelved after a different site was chosen for the stadium. The Seattle city government commissioned a new study in 1979 to examine improvements to the monorail system, including a closed loop around the Seattle Center campus and an

after a signature-gathering campaign. Falkenbury's proposal envisioned an X-shaped system with service from Downtown Seattle to
Ballard,
Lake City, the
Rainier Valley, and
West Seattle, which would cost $850 million to construct ($ in dollars). 53 percent of voters approved the monorail plan, named Initiative 41, in a general election on November 4, 1997, creating the Elevated Transportation Company (ETC) to seek financing.
The city government appointed a board for the ETC (later renamed the Seattle Monorail Project) and funded early planning work, but did not agree to fund a $4 million feasibility study in 2000. The original monorail initiative was repealed and replaced by a new plan approved by voters in November 2000, which included $6 million for a study. The first corridor, the "Green Line" from West Seattle to Ballard, was estimated to cost $1.75 billion; a
motor vehicle excise tax would fund it. The tax was adopted through a ballot measure that voters narrowly approved in the November 2002 election, creating the Seattle Popular Monorail Authority to manage the program.
The monorail project initially attracted two bids led by

and
Bombardier, but both pulled out in April 2004 over cost concerns and the availability of local contractors. The project was stymied by tax revenue that was lower than expected and design changes to keep construction costs within the proposed budget and open by 2009—a two-year delay from the original plan. A
recall measure on the November 2004 ballot aimed to prevent monorail construction, but voters rejected it, allowing the expansion project to continue. The monorail operator reached a tentative agreement with Cascadia Monorail to build the system in June 2005 but had not published the full financial analysis required by the city government before construction was permitted to begin. A revised cost estimate of $11 billion, including debt payments until 2050, was unveiled later that month and withdrawn by the Seattle Monorail Project after public criticism from elected officials.
The monorail project, including a $4.9 billion financing plan for a line, was abandoned after a fifth ballot initiative in November 2005, when 64 percent of voters rejected it. The Seattle Monorail Project was formally dissolved in January 2008, having spent $124.7 million on planning and property acquisition. The "Green Line" corridor from West Seattle to Ballard was later included as a light rail project in the
Sound Transit 3 ballot measure, which was passed by voters in 2016.
The light rail line, scheduled to open in the 2030s, incorporated some elements from the monorail plan into its early project feasibility studies.
Accidents and incidents

On October 20, 1962, the penultimate day of the Century 21 Exposition, the red train struck a
bumper stop at the Westlake terminal—the first accident on the monorail system. None of the 400 passengers were injured, but the train's window and nose were damaged, requiring a patch and two hours of repairs before returning to service. The red train was damaged in a similar manner on August 14, 1963, striking the Westlake terminal's bumper while on a test run after the first set of brakes failed.
The first major accident involving the monorail occurred on July 25, 1971, when a brake failure on the red train caused it to strike a girder at the end of the track in the Seattle Center terminal. The train struck the girder at , injuring 26 of 40 passengers. The red train was lifted off the track and moved to a Seattle Transit System maintenance facility in August for a complete rebuild of the front car at a cost of $100,000 (equivalent to $ in dollars). This was completed in June 1973 with the help of translated
blueprints from Alwac. One maintenance worker was killed during the repairs after falling into a pit under the vehicle.
A similar incident on the blue train occurred on May 21, 1979, injuring 15 people at the Seattle Center terminal. The monorail's brake system was not found to be at fault, but the disabling of the onboard speed control system was criticized by city officials. The monorail struck a bumper at the temporary downtown terminal on August 27, 1987, causing no injuries but breaking the glass window, which fell onto a parked car below. The incident was later blamed on driver error.
On May 31, 2004, a fire broke out on the blue train as it passed through the Experience Music Project with 150 people aboard; eight suffered minor injuries. Passengers were evacuated using ladders deployed by the

. The electric current melted through the shoe's aluminum housing and arced, causing sparks that ignited the undercarriage's grease and oil, creating a fire that entered the interior and ignited the seat cushions.
The red train re-entered service on December 16, while the blue train returned on May 2, 2005, after extensive repairs.
The two monorail trains clipped one another on the curve above 5th Avenue and Olive Way near the Westlake Center terminal on November 26, 2005, at around 7:10 p.m. The southbound blue train's driver caused the collision when they failed to yield while entering a gauntlet track north of Westlake created by the 1988 renovation.
The two trains carried 84 passengers who were evacuated using firetruck ladders, including two people hospitalized with minor injuries. Within a week, the trains were separated and towed via crane to the Seattle Center terminal to undergo extensive repairs that cost $4.64 million ($ in dollars), funded through an insurance payout and contributions from the federal government and the private monorail operator.
