By 1939 it was being used as a pay bus. In 1947 FP4 was returned to Commonwealth Engineering and fitted with a canopy roof. During 1965 it was loaned to the Way & Works Branch for use on track inspection on the branches in the Werris Creek area. A fractured chassis caused its withdrawal from service in September 1967. It was written off in November 1969 and scrapped in December 1970. FP5 (1st) FP5 entered service in September 1937. By 1939 it was being used as a pay bus. FP5 was destroyed by an explosion in a payroll robbery attempt at Yanderra on the Main South line on 8 December 1941. This attempted robbery killed all three rail employees that were aboard the pay bus at the time of the explosion. The remains of FP5 were written off in 1942. FP6 & FP5 (2nd) These 2 rail buses saw a return to having only a driving position at one end only along with only having a door on one side. The door on these buses however was a siding door instead of the swing door on the previous rail buses. FP6 FP6 entered service at Harden in September 1937. By 1939 it was being used as a pay bus. It was withdrawn from service in May 1968, condemned on 3 November 1969 and scrapped in December 1970.

The chassis was based on a 1942 Ford truck chassis and a hydraulic braking system was fitted. FP5 (2nd) was also built as new as a pay bus and entered service in September 1945. FP5 was stored in October 1968 but was recalled for use at Newcastle in July 1969. Due to poor condition it was stored again on 20 October 1969, withdrawn on 3 November 1969 and scrapped on 5 December 1970. FPs7-12 To replace the aging fleet of existing pay buses, six new pay buses were ordered from Commonwealth Engineering in 1967.
