The A.E.Goodwin Coy., of New South Wales were only successful in obtaining one order for rolling stock from the Queensland Railways. This was for 200 bogie louvered wagons, numbered 30942 - 31141, built to design number 6252 and delivered between March 1956 and March 1958. This also, was the first louvered type vehicle of all steel construction to run on the QR system. Although delivered with draw hook type couplings they were later fitted with a automatic type and reclassified BLCT. Our example, 31073, entered service during August 1958. Being available for passenger trains these vehicles were often seen on Air-Conditioned trains but were more popular in the northern fruit express 247D which used to depart Roma Street Yards each day Monday to Friday almost wholly made up of this type of wagon. With the introduction of more modern stock, the BLCT class were relegated to secondary duties with quite a few being allocated to various maintenance gangs. In July 1993, 31073 arrived at QPSR for use at Swanbank. It was written off books by the Queensland Railways during September 1994.
