|
Description |
The general description applies to all Ruston and Hornsby models. The locomotive is powered by a Ruston diesel engine (of two cylinders in the smaller size and three cylinders in the larger - see above), mounted on a steel frame which is fitted with four steel rail wheels The wheelbase is short to facilitate work on acute curves. The driver's seat is fitted sideways to give vision in both directions. Three forward speeds and three reverse speeds are provided. The chief use of the locomotive is to haul wagons on light railway track of 2 ft. gauge, which is used to a great extent on quarry work where it is more or less permanently in one position and moved infrequently. For general work on airfield construction, if the ground is too soft for lorries and dumpers, the locomotive can be used for hauling wagons containing excavated material to a tip. The disadvantage of using railway track on this type of work is that the track requires constant attention to keep it in good order and, as the tip grows, the track has to be moved. Sanding gear is provided on the locomotive to assist adhesion in wet weather. |
