Following suggests you admire the side buffers on the QLX as that means not bogie exchangable. Another point is containers were coming into use around that era, so removing the need for bogie exchanges as a load of perishable traffic in a container on a QR wagon was easily swapped to a standard gauge wagon without the expense of a bogie exchange facility.

Railway Digest May 1972
150 of the Queensland Railways QLX code were ordered in 1969 from Comeng (Qld) and Scotts of Ipswich. As the "X" indicates, they were designed to conform with ANZR specifications for bogie exchange vehicles, with the exception of the side buffers, which were necessary to permit use with other QR goods stock, the majority of which still has side buffers and screw couplings. The auto couplers fitted to the QLX  also have transition links. The QLX will not be used in bogie exchange traffic until sufficient goods stock is converted to auto couplers, enabling removal of side buffers.
