In 1968, an order was placed with Tulloch Limited for 10 railcars for the Riverina Express with the fleet delivered between October 1970 and May 1972.

The objective was to provide two four-car trains, each consisting of one PCR and three PCH along with one spare car of each type.

The purpose of forming the trains with individual railcars was to allow it to divide at major stations along the route where cars detached for Cowra, Tumut, Lake Cargelligo and Hillston on selected days, as well as the traditional destinations of Griffith and Albury.

In 1977 four were converted to operate an exhibition train around New South Wales for the Silver Jubilee of Elizabeth II.

Three more were pooled with the 1100 class railcars on Illawarra line services while the car with a damaged engine frame became an office.
