By the London, Midland and Scottish line there has just been introduced a novel railroad travel unit styled the “Ro-railer,” which in its appearance differs little from the conventional road motor coach. It seats 26 passengers, and its engine, developing a maximum horse-power of 120, is equipped with a supplementary gearbox giving increased speeds on long railway runs with lower engine speed. To enable the “Ro-railer” to run on either rail or road, special flanged rail wheels are fitted to the axles. On the outside of these are placed pneumatic-tyred road wheels, mounted on eccentrics fitted to an extension of the axles through the rail wheels. When on the road, the road wheels are locked concentrically to the rail wheels, which are of smaller diameter, and clear of the road. When on the rail, they can be raised by giving them half a turn. They are then locked to the chassis, and do not revolve. For road to rail transference, the “Ro-railer” is driven on to the rails at any point where the road has been made up level with the railtops. Then, with the rail wheels directly over the rails, it is driven forward for a few yards. On reaching the point where the made-up road is tapered off, the rail wheels gradually come in contact with the rails and take the weight of the vehicle off the road wheels. The changeover normally occupies from two and a half to five minutes. The “Ro-railer,” built by Karrier Motors, Ltd., of Hudderfield, has been designed principally for branch-line operation, and one would imagine a handy vehicle of this description would be of real service in a country like New Zealand. The system is, of course, equally applicable to freight transport, an ordinary truck body being then employed in place of the passenger body.
