The limited information I am aware of is at least one van was bogied exchanged and sent to Sydney as part of the Trial. I have read unsubstantiated accounts several vans were bogied exchanged and sent south?
What I wish to know is the number of the van/vans that made it to Sydney so I can model one of these.
NO Pressure Sulla 1 as you have a deep understanding of Queensland Rail Activity and History.
I have included a draft below of something I wrote several years ago that has not progressed as I am short of facts regards Wagon numbers and a strong edit is required to the text.Another Day!
"The Wentworth report of 1956 recommended in essence building a National connection of Standard Gauge lines either by conversion of existing lines or new construction connecting all mainland Capital Cities.
This was a compromised outcome lessening the recommended gauge conversion of the Australian System headed by Sir Harold Clapp in 1946.
My comment from an Australian Railway enthusiast and Railway devotee what a moment we missed by not adopting Sir Harold Clapps recommendations.
History records, moving on!
With the National uniformed gauge euphoria Railways of Australia becaming the central authority of limited power to recommend uniformity of design with new items of Rolling stock.
Bogied Rolling stock was designed with the knowledge these wagons would run to every mainland state of Australia and would therefore have to be within the loading gauge limits of each states standard gauge trackage.
There were many wagons built by the Government Railway administrations and private Engineering Companies especially after the opening of the lines allowing Sydney to Perth on one gauge.
The Victorian Railways in the first ten years of uniformed gauge from Melbourne to Sydney experienced a ten percent increase in tonnage year upon year as well the Administration built more than twelve new designs of wagons to meet this unprecedented demand.
The Queensland Government Railways (QGR) due to their modest loading gauge inherited from bad decisions in the 19th century were unable to join the unification as other state systems could however they came up with a compromised solution.
In 1964 the QGR were taking delivery of bogied GLC class wagons louvred vans. It was a simple decision and task to modify these wagons to allow the bogies to be changed out for standard gauge bogies and therefore to denote this the wagons were reclassified QLX.
The QLX code meant Q for Queensland, L for louvre van and X showing the wagon was suitable for bogie exchange.
A trial trip; other people believe several trips were made between Brisbane and Sydney for evaluation.
Either way all agree only a hand full of trips were made.
Little information seems to be available regards the success of the trial.
A Bogie Exchange facility was never built in Brisbane and the whole prospect of the QLX vans regularly travelling throughout Australia on the Standard gauge network did not eventuate.
A pity, we can only speculate on the reasons why the concept was not progressed.
