The 620/720 class railcars entered service from 1961 being built at the NSWGR Rollingstock workshop Chullora. Their design was based on the earlier 600/700 class railcars which had successfully replaced many steam hauled services throughout NSW. The construction techniques utilised in the 620/720’s included engineering principles and skills employed by the Chullora workshop for the construction of aircraft components during World War II. Bogies for both power and trailer cars were manufactured by A.E. Goodwin. A total of 18 two car sets were built.

service, Units 621/721 to 625/725 were built as all Second class units
coded NPF/NTF. The units of the second order, units 626/726 to
were intended to also be utilised for longer distance services and were
with a first class section in the trailer car, which was hence coded
Two further sets, 630/730 and 631/731, intended for outer
Units 632-633/732-733 & 635/735 were constructed with a luggage area to accommodate 4 tons of loading in the power car. These sets were intended for service in the Goulburn – Cowra – Lithgow area and their unique original configuration could be identified by a blank panel on the power car between the 3rd and 4th side windows.
Units 634/734 & 636-637/736-737 were also constructed for country operation intended to replace the remaining steam hauled services in the Dubbo area and allow the transfer of 600/700 sets to other duties. A large luggage area of 7 tons capacity occupied half the power cars and their external appearance differed with a “blank” panel being positioned adjacent to the central radiator compartment.
The final set constructed was unit 638/738 which was destined for operation on the Murwillumbah branch. As it was required to haul a parcel van, the unit was built with larger motors and extra fuel capacity but used the same seating and luggage configuration as the early series cars.
Several other variations can be noted between car groups construction with other changes also being implemented throughout their careers.

620/720 sets were built with rectangular windows in the passenger doors
the earlier 600/700 class cars. The remainder of the cars were
with circular ‘porthole’ windows in the passenger doors.
The railcars were originally turned out in an Indian red livery with buff lining on the metal bands above and below the windows, as well as decorative line work at the ends, which carried around onto the lower body panels. The roof was metallic silver/grey in colour and the under gear was black. The car gutter strips were painted black and the end pilots silver.
Standard NSWGR shaded lettering was used to denote car number & classification, smoking or non smoking designation and seating class allocations on each car side. The car number was also shown at the top of the end doors.

Between 1969 and 1971, the all Second class NTF trailers were converted to composite NTC type, and around this time the livery was simplified on all cars by omitting the buff line above the windows.
From 1980, four
620/720 sets were painted in the yellow ended ‘Reverse’ livery with
625/725 & 637/737 also having a yellow band applied along the lower
of the car.
In 1982 the ‘Candy’ colour scheme was introduced which consisted of a bright red body, with broad white and orange stripes along the lower body side, and a thin yellow stripe separating the red from the orange. Bright silver was applied to the roof roof and pilot, and the underside, running gear and the bottom of the lower body panels was painted black. All handrails and lettering were painted white. In January 1985 629/729 were painted this way.

The fitting of reinforced glass windscreens for the driver/guards cab position windows which projected beyond the body line significantly altered the cars appearance and were hence referred to by some as “Bug eyes”.

The final six operating sets progressively began to enter storage during 2007 as new Hunter rail cars were introduced into service. The last day of revenue service for the 620/720 railcars was on June 2nd 2007 with the mismatched set 621/725 performing the final run to Dungog.
