The success of these small vehicles to deliver an efficient and economic pay service prompted NSW Railways to order a second fleet of Pay Buses in 1967 to replace the ageing first fleet. The order was extended for a further vehicle FP13, which operated as a rail bus on the Cooma-Bombala line but in 1980, it underwent a conversion to a Pay Bus.

Built by Waddington's successor, Commonwealth Engineering (NSW) Pty Ltd at Granville, and introduced in 1968, the new fleet had longer and squarer bodies and could be driven from either end. They featured a standard road bus front profile, weighed considerably more and were powered by Leyland diesel engines. The last recorded delivery of wages from a Pay Bus was on the Cooma run in the Monaro region on 1 April 1986.

The Second Fleet Pay Buses were all double ended and their livery was Indian Red with chrome yellow lining, which had been adopted as the New South Wales Government Railways standard for all new main-line diesel-electric locomotives in the 1950s.

FP7 is the only Pay Bus known to have carried royalty. After a major refurbishment in 1970, it was used to convey HM Queen Elizabeth II and her party between Coffs Harbour Jetty and Coffs Harbour Station.

FP13 was built specifically as a passenger rail bus for use on the Cooma-Bombala run and not converted to a Pay Bus until 1980.

Because of the many sharp curves on that track, FP13 was limited to travelling at 39 miles/hour (64km/hour).
