WAGR official photo showing new CXB class wagons (RHWA collection)

The CXB class sheep trucks were the final class of four-wheeled sheep truck built for the W.A.G.R. They used the post-war standard 18'-0" chassis and the extra 2'-0" in length increased the capacity by 14 sheep over the CX and CXA classes. It seems a little odd that they were not given a two-letter classification as most of the C group classes remained unused. All three hundred wagons (17401-17700) were built in 1953 by Hoskins Engineering. The decline in live sheep traffic meant that by 1960 some wagons were surplus and available for conversion. Disposal of the class was as follows:

1960	17403, 17404, 17445, 17498, 17513, 17535, 17543, 17556, 17576, 17599, 17633, 17695 to NF 22801-22812
