NARROW-GAGE GASOLINE CARS FOR AUSTRALIA The McReen Motor Car Company, Omaha, Neb., re-cently completed and shipped five 200-hp all-steel motor cars from its works to the Queensland Gov-ernment Railways in Australia. These lines are 3-ft. Complete dismantling of the cars followed theirconstruction, the cars being shipped knocked down. The. Narrow-Gage Gasoline Car—General View manufacturers will send an expert to superintend the re-erection of the cars in the railway companys shops atIpswich. This gasoline rolling stock conforms to theMcKeen standard design and construction with the excep-tion of some special features which are necessary to meetthe requirements of the Queensland Railways. These ex-ceptions include the fact that the position of the operatinglevers is reversed for left-side control, and the side type ofbuffing gear with draw hook and screw couplings displacesthe M. C. B. couplers. The depressed center entrance is constructed so as toprovide accommodations for handling passengers at bothelevated and roadside platforms with equal facility. Themotor-truck wheelbase is limited to 6 ft. and this, in com-bination with the specially designed front body and truck
