The plan of running loaded waggons from a narrow gauge railway, on to trucks that work on the broad gauge lines, is of course one of facility; but it is only applicable for the transmission of goods from the narrow to the broad gauge. The attempt to carry loaded broad gauge waggons upon trucks on the narrow gauge rails, would be preposterous, as it would necessitate all the broad gauge lines to be provided not only with their large trucks, but a stock of narrow gauge waggons, or they would be unable to transfer the goods on to the narrow gauge rails, except occasionally. But even with regard to the passage from the narrow to the broad gauge, the system will not bear examination. "If the trucks are supported on springs, there is practically a difficulty in running the waggons upon them; and if they are not supported on springs, they will sustain great injury on the journeys. If they are loaded singly, there will he a great delay; if they are placed in a row, and the narrow gauge carriages are run through the whole series, very great caution will he necessary to secure each carriage both in front and in rear." For the foregoing as well as other considerations, the commissioners reject the proposal as entirely inapplicable to the traffic of railways.
