Zillertalbahn
Detail shot of 760mm gauge converter wagons at Jenbach on Saturday September 15th, 2001. This shot shows that these small wagons are indeed bogie wagons and that coupling is done using a shaft and pins.
Notice how the wagon side frame forms the railhead surface for the standard gauge cars.
