and a single Mack tow truck. ACTION's heritage fleet consists of a 1949 AEC Regal III and a 1961 AEC Reliance. History Until the mid-1970s, purchases mainly comprised heavyweight British built AEC and Leyland chassis before a switch was made to European chassis. In 1972, the first Volvo B58s were purchased. These were followed by MAN SL200s from 1975, articulated MAN SG192s from 1976, Mercedes-Benz O305s from 1981, articulated O305Gs from 1982, Renault PR100.2s from 1986, articulated Renault PR180.2s from 1988 and Renault PR100.3s from 1994. The Renaults were badged as Macks although they carried the Renault diamond badge. Although primarily purchasing new buses, ACTION has on occasions purchased and hired second-hand buses. With industrial action in England causing a shortage of both chassis and parts at a time Canberra was undergoing phenomenal growth, in February 1974, 12 Leyland OPS2/1s were hired from the Public Transport Commission. In June 1974 the entire 10 bus fleet of Bedford, Ford and Thornycroft buses of recently ceased operator Bowden's Bus Service of Tamarama was purchased. A number of Bedfords and Fords were purchased from dealer's stock. In 1997, 25 Wright Crusader bodied Dennis Darts were imported from Northern Ireland. In 2001, 17 former North & Western Bus Lines Hino RG197Ks were leased from Sydney Buses for a short period. In February 2004, 20 Custom Coaches bodied Irisbus Agoras built for, but not delivered to King Brothers entered service. Livery Fleet livery was originally fawn with a yellow stripe. This was replaced by the 1960s by a coffee body with arctic green window area and red stripe. In 1973, a yellow body with arctic green window surrounds and light blue stripe livery was introduced. This was replaced in 2004 by the current white, green and orange livery. Registrations Initially buses were registered in the C**** series. By the 1960s, buses were registered as ZIB*** in the Commonwealth of Australia series. In May 1989, the fleet was reregistered onto ACT Government BUS*** plates.
