1904-1920: Wagons to school buses
At the beginning of the 20th century, Don M. Brockway found himself working at the first hardware store in Los Angeles, California; to supplement its income, the hardware store also sold parts for wagons and carriages In 1904, Brockway founded Crown Carriage Company, producing purpose-built horse-drawn carraiges. While the first vehicles were built in a wooden shed, the company moved to a brick factory in 1910.
After 1910, as carriages gradually became "horseless", Crown experimented with building truck bodies. In 1916, the company built its first bus body for transit use; it was an open-air design heavily influenced by wagon design. After World War I, Crown built its first body for school bus use.
1921-1945: Metal bodies and Supercoaches
In 1921, a major shift in company production occurred as Murillo M. ("Brock") Brockway, the son of the company founder, was put in charge of school bus production. Viewing school buses as a growth market in the suburbs of southern California, Brockway discontinued all wagon production in favor of bus and truck body production. To expand production and improve shipping of its vehicles, a much larger factory in Los Angeles was opened in 1923.
In pursuit of developing heavier-duty and higher-capacity school buses, Crown introduced the first school bus with dual rear wheels in 1927. In 1930, it produced its first all-metal school bus body (on a Mack chassis), with a 43-passenger capacity.
1932 would mark several major changes for the company. As part of his taking over day-to-day operations of Crown from his father, MM Brockway introduced a ground-breaking school bus body; elements of its design would change school bus design forever. To improve forward visibility, the new bus was a cab-forward design, with the driver sitting next to the engine and radiator. To improve safety, the bus was designed with a integral chassis; the windows were mesh-reinforced safety glass. Alongside the standard braking system, the bus also was equipped with two backup braking systems. In 1935, the cab-forward school bus was updated and dubbed the Crown Supercoach.
For 1937, to increase seating capacity to 79 passengers, Crown produced its first mid-engine Supercoach; the bus came with a Hall-Scott gasoline engine. In 1939, Crown acquired Moreland Motor Truck Company; as part of the acquisition, Crown moved to a larger factory in Los Angeles. Additionally, the Supercoach was changed from a mid-engine to a rear-engine configuration for 1940.
1950-1980: Mid-engine school buses
In the United States during the years immediately following World War II, population growth of suburbs expanded, fueled by the post-war baby boom. As that segment of the population entered school, demand for new schools (and school buses to take them there) rapidly rose. In 1946, Crown began development on an all-new mid-engine Supercoach. While heavily influenced by motorcoach design, Crown intended it primarily for school bus use. Introduced in 1949, the all-new Supercoach used unit-body construction with high-strength steel in place of a separate chassis; to combat corrosion, all body panels were aluminum.
To prove the durability of the Supercoach to potential customers, Crown sold the vehicle with a 20-year/100,000 mile warranty for the body.
During the mid-1950s, several changes were made to the Supercoach. In 1954, the Cummins NHH diesel engine was added as an option, becoming the first diesel-powered Supercoach. A year later, the tandem-rear axle Supercoach made its debut; the largest school bus of its time, it held up to 91 student passengers.
From the 1950s to the 1970s, the Crown Supercoach and the similar Gillig Transit Coach became two of the most common school buses throughout the West Coast of the United States. Although conventional-type school buses remained in demand, the development costs did not justify starting up an all-new model line. To supplement its income, Crown served as the West Coast distributor for other manufacturers, including Wayne, Blue Bird, and Thomas Built Buses; Crown also marketed Prevost motorcoaches alongside its own coach buses.
In 1979, the Brockway family sold Crown Coach Corporation to a local truck distributor; this would begin a sequence of several ownership changes. During 1984, Crown moved from Los Angeles to Chino, California in San Bernardino County. To diversify beyond school buses, Crown entered into a joint venture with the Hungarian firm Ikarus to produce articulated mass-transit buses. The Crown-Ikarus 286 was bodied in Hungary, with final assembly finished by Crown in California, with the fitments of American-sourced powertrains and interiors. In 1986, the partnership ended, with only 243 buses produced.
By the end of the 1980s, the Supercoach had been in production with only minor changes for nearly 40 years. As Crown prepared the Supercoach to use a methanol-fueled version of the Detroit Diesel 6V92, major changes to the bodyshell were necessitated. The rear-mounted engine required new rear bodywork to fit inside, which forced a complete change to front body to match. Although not an all-new design, the Series II, as it was named, was the first major update to the Supercoach since 1948.
After its acquisition, operation ceased in 1991. Crown's difficulty in competing with manufacturers of smaller, less durable but cheaper school buses was cited by company president Bruce Freeman in October 1990 as a primary factor in GE's decision to leave the school bus market.
From 1951 to 1985, Crown Coach Corporation was also a manufacturer of fire apparatus under the Firecoach brand, with the majority of Firecoaches being sold to west coast departments, especially in California. Beginning in 1972, two different Los Angeles Fire Department (LACoFD) 1965 Crown Firecoach engines were used to portray Engine 51, during the first two seasons of the NBC/Universal television series Emergency!. Engine 60, which was the fire engine stationed at Universal, was used for scenes filmed at the Universal lot, and Engine 127 was used for scenes filmed at Station 127 where location filming was completed. In 1974, LACoFD purchased a large number of P-80 Ambassador pumpers from the Ward LaFrance Truck Corporation, and the company opted to donate an additional, identical unit to Universal for use as Engine 51 on the show, thereby allowing LACoFD to discontinue taking the Crown Engines 60 and 127 periodically out of service for filming. Engine 127's Crown Firecoach was later destroyed in a traffic accident, however Engine 60's Crown Firecoach, as well as the donated 1974 Ward LaFrance, are now owned by the County of Los Angeles Fire Museum Association and have been fully restored.
