In 1981 a group of tankers numbered JPB 14589, 14592-6 were built with the final member of the class (14590) being issued to traffic in 1982. Two of the class, 14591 and 14597 were issued as class WJPB on standard gauge bogies. They were all owned by Bain Leasing Pty Ltd. In 1985 WJPB14591 was converted to narrow gauge class JPBA. The rest of the class were converted to JPBA in 1986. In 1987 JPBA 14589, 14594 and 14595 were converted to standard gauge as WJPB, followed by 14592 in 1990. 14589 was converted back to narrow gauge as JPBA in 1990. In 2010, 14590-14597 were listed as Standard gauge class ATBY but 14589 was not listed.
