The 1000 series of buses were built in 1947 and 1948 and were purchased in 1960 from Key System Transit Lines.

The 1300 series of buses was built in 1946 and were purchased in 1960 from Key System Transit Lines. Twenty of these buses were rebuilt with diesel engines in 1961 and renumbered in the 1200 series.

The 1200 series of buses were rebuilt from 20 1300 series buses purchased in 1960 from Key System Transit Lines. The buses were rebuilt with diesel engines in 1961 and were assigned numbers 1200, 1202, 1203, 1205, 1209, 1212, 1213, 1215, 1217, 1220, 1224, 1228, 1230, 1232, 1233, 1234, 1235,1236,1238 and 1241 by replacing the “3″ with a “2″.

The first 1500 series was purchased from Long Beach in 1961 to provide engines and parts for conversion of 1300 series buses to diesel operation. Originally gas powered, these buses had been converted to diesel in 1954. Numbers were vacated after parts were removed. Long Beach numbers were 7011, 7012, 7014, 7021 and 7022. After these buses were stripped of parts, units 7012 and 7022 were used as storage facilities at 45th and San Pablo yard until around 1980.

In March 1966, AC Transit unveiled its “Freeway Train” an experimental articulated bus that seated 77 passengers. The bus was created by modifying a heavy-duty over-the-road Trailway bus.

GMC bus 666 was converted to steam power and run in a one-year test program that ran from September 27, 1971 to Sept 29, 1972. At the conclusion of the test, the bus was converted back to diesel operation.

This prototype Neoplan double-deck bus, a big brother to the standard 40-foot coaches then in use by the District, was on loan to AC Transit for road-testing in April 1983. The double-decker is only 40′ long, but at 13′ 6″ was taller then any other bus ever run by AC Transit. The prototype’s internal configuration — a layout designed for long-distance touring service — included 73 seats, with 53 of them on the upper level.

AC Transit 999 was a futuristic hybrid electric bus —  battery-powered with a clean-burning, propane auxiliary generator that was tested for six months in 1999.

Hydrogen-powered bus 4285 was built for SunLine Transit Agency and run by them until February 2003 at which time it was returned to UTC Power for modifications. In mid-2003, AC Transit began road testing this vehicle with tests concluding in October 2004. To support this project a hydrogen fueling facility was built at AC Transit’s Richmond Division.

Designed in partnership with Van Hool, UTC Power, and ISE Corporation, AC Transit’s fuel-cell bus represents the most advanced, fuel-efficient, zero-emission, hybrid-electric, hydrogen fuel cell bus in the world.

This partnership modified the 40-foot Van Hool A330 bus chassis to accommodate UTC’s PureMotionTM 120 kW fuel cell power system and ISE’s hybrid-electric drive system. Hydrogen tanks on the roof give the bus a range of 300-350 miles, and batteries that are recharged during braking can provide an extra 95kW of power for acceleration and climbing steep grades.

These buses were introduced to the public at the International Transportation Expo in Dallas Texas on September 26, 2005 and entered revenue service with AC Transit on March 20, 2006.
