context_page_description: The railways of New South Wales, Australia, use a large variety of passenger and freight rolling stock.
context_section_description: In 1966, after the success of the Tulloch double-deck trailers, tenders were called for double deck motor cars. In 1968, four experimental double-deck motor cars (C3801–3804) were built by Tulloch and entered service enabling the first eight-car double-deck train, set S10, to operate by marshalling them with four Tulloch trailers T4839, 4840, 4843 and 4844. These were the first fully double-deck Electric Multiple Unit passenger trains in the world.
  Each power-car carried electrical equipment from different manufacturers for evaluation purposes: C3801 (Mitsubishi), 3802 (Toshiba), 3803 (Hitachi) and 3804 (English Electric). Set S10 proved unreliable and the single-deck "Sputnik" C3701-series power-cars often deputised for Tulloch power cars out of service. In 1977, it was decided to disband the set to convert them to trailers. C3801 was converted to T4797 in 1980 and C3803 became T4799 in 1982. Conversion of C3802 to T4798 was started at Elcar Workshops, but never finished and it was later scrapped. C3804 is now preserved at the NSW Rail Museum, Thirlmere. It was withdrawn from service on 4 January 1980.
  These trailers operated on the:
  South Line – City Circle to Macarthur via Granville
  Inner West Line – City Circle to Liverpool via Regents Park
  Bankstown Line – City Circle to Liverpool via Bankstown
  East Hills Line – City Circle to Macarthur via Sydenham (then via Airport Line in 2000–2003)
