In 1955, during an intermediate phase of the replacement of the narrow-gauge ({{track gauge|1067mm|disp=or}}) [[Port Pirie Junction railway station|Port Pirie]] to [[Marree railway station|Marree]] railway with a [[standard gauge]] line, train-lengths of standard-gauge flat wagons were fitted with [[narrow gauge railway|narrow-gauge]] rails, allowing narrow-gauge trains carrying coal (from [[Leigh Creek Coalfield|Leigh Creek coalfield]]), livestock or general freight to travel more quickly by standard gauge on the new, well-engineered alignment. The rails on the flat wagons were continuous, so that the upper train could be rolled on and off in one piece.<ref>{{cite book| title=Uniform Railway Gauge| first=Eric| last=Harding| publisher=Lothian Publishing| year=1958| page=14}}</ref> The leading wagon on the narrow-gauge train was also secured to anchoring on the front wagon on the standard gauge train.<ref>{{cite book| title=Tales from a Railway Odyssey| authorlink=Keith Smith (engineer)| first=Keith A.| last=Smith| page=114}}</ref> [[Air brake (rail)|Air brakes]] on the narrow-gauge train were connected to the standard-gauge train's air brakes. A narrow-gauge locomotive pushed the narrow-gauge train up an earthen ramp to the deck of the standard gauge train.  There were no overhead structures to restrict operation of the trains.
