Initially it was all sleeping class with only irregular way side situp passenger accomodation being provided. In the 1960s regular situp was provided, but this was eventually withdrawn. Situp was again introduced in 1981 when it was added to the Trans-Australian and Indian Pacific services.
In 1983 the Trans-Australian was reduced from 4 to 3 services and the economy class sleeping cars were replaced by additional first class cars. Later the same year another Trans-Australian service was removed so that The Alice train could be inaugrated.
