black horizontal lining. The SAR streamlined some of its 500 class locomotives for the makeover. In 1941 Victorian steam locomotive H220 was introduced to service, intended to haul the train but never entered regular service due to weight restrictions. For over 40 years Victorian Railways used A2 class locomotives, usually in pairs. Post-war history In 1946, a new style of sleeping compartment was being tested, and a mock-up of part of a carriage was built for display in Melbourne and Adelaide. The carriage portion was externally painted in green and black with yellow. The sleeping cars were of two types. Twinette cars had two-berth compartments (as had the E and Mann cars before them), but each compartment had an adjoining toilet and shower room; roomette cars had single-berth compartments either side of a central aisle, and a shower room at the end of the car. The maroon sleeping cars from 1949 onwards were 16 in number, later 18, and were given Aboriginal names that were painted on the sides of the cars. The eight roomette cars were Allambi, Chalaki, Juki, Mururi, Nankuri, Purpawi, Tantini, and Tarkinji; the ten twinette cars Dorai, Kuldalai, Malkari, Mokai, Nomuldi, Paiti, Tawarri, Weroni, Yankai, and Yanni. From 1949 the train moved into the modern era, with new air-conditioned Corten steel carriages gradually entering service, in maroon with a fluted stainless steel panel on each side and a black roof. This livery remained until the 1990s. On 7 September 1951, the westbound service collided with the eastbound service at Serviceton station with four A2 class locomotives destroyed and one fatality. Diesel locomotives took over in 1953, with the introduction of the South Australian 900 class and Victorian B class. The superior acceleration of the latter allowed 70 minutes to be shaved off the journey time without exceeding the 60 mp/h limit. These were superseded by the 930, S, X and N class locomotives. Twinette cars Tawarri and Yankai were added in 1967, and these also followed the newer style of interior. Thus from the early 1970s onwards in the newer style there were two roomette cars, Allambi and Tantini, four twinette cars, Dorai, Tawarri, Weroni, and Yankai. In 1971, roomette cars Allambi and Tantini and twinette cars Dorai and Weroni were sold to the Victorian Railways for use on The Vinelander to Mildura, and replaced with new carriages. They were repainted dark blue and their names
