Ruston and Hornsby Diesel Loco, 33/40 hp, 2 ft Gauge

Description	The locomotive is used to haul light railway wagons where the track is permanently installed or is only moved infrequently, as for example, in quarry work. It may also however, be used in airfield construction and similar classes of work when the ground is too soft for lorries and dumpers although in this instance the track will require more attention to keep it in order and will have to be moved as the work progresses The locomotive is powered b a Ruston 33/40 Ii p diesel engine This entry has been amended up to AL14, 2nd Edition

Ruston and Hornsby Diesel Loco, 16/20 hp, 2 ft Gauge
No photographs currently available
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.

Monks Hall Light Railway Track

Description	The track is made in lengths of 18 or 15 ft., joined together with the fishplates and fishplate bolts. The steel sleepers are bolted underneath the track at intervals of 3 ft., but are placed closer together on curves. Turnouts left-hand and right-hand can be used for enabling tracks to branch off. Turntables are used so that right-angle turns can be negotiated. A jim crow is provided for bending straight rails into curves. A punching bear is also provided for making holes for fishplate bolts in lengths of rails that have been shortened by cutting with the rail saw. This entry is amended to AL18, 2nd Edition.
Data	Type of rail - Flat-bottom, bull-headed section, 20 lb to the lineal yard. Gauge - 2 ft Weight (one mile of track, complete with sleepers, fishplates, clips and all nuts and bolts) - 41¾ tons. For one mile of track in 15 ft. lengths the following are required :- 704 pairs fishplates. 7,040 clip bolts. 7,040 clips. 2,816 fishplate bolts and nuts. 1,760 sleepers.

Hudson LH and RH Turnouts, 2 ft Gauge

Description	Left- and right-hand turnouts are used in conjunction with the light railway track, shown above, to enable wagons to be moved from one track to another. When ordering turnouts it is advisable to order additional pairs of fishplates and bolts, unless similar spare fittings have been ordered with the main track, as each turnout usually needs six extra pairs for connecting up the track. This item of equipment appears to have been added to the 2nd Edition by the issue of AL18.
Data	Gauge - 2 ft Weight of rails - 20 lb. per lineal yard Approximate radius - 37 ft Approximate angle of crossing - 1 in 3 Weight of turnout - 575 ft Overall dimensions: - Length - 15 ft. 0 in. Width - 6 ft. 3 in. Height - 4 in.

Hudson 1 cu yd, Type A and 2 cu yd, Type B double-sided Tipping Wagon, 2 ft gauge.

Description	These double-sided tipping wagons are used in airfield construction, and similar classes of work, for transporting excavated earth, sand, etc. The wagon consists of a body supported on a cradle, which is mounted on a steel frame provided with four flanged steel rail wheels. The wagons may be connected together by link couplings. This item of equipment appears to have been added to the 2nd Edition by the issue of AL18.
Data	Model - Type A (1 Cu. yd.) and Type B (2 cu. yd.) The Type A wagon is the maker's lightest model and is suitable for carrying soft materials loaded by hand it is not intended to be used for hard materials or broken stones; and the wagons are not designed to withstand rough shunting by locomotives. The Type B wagon has stronger body plates and may be used for hard materials such as broken stones. Gauge - 2ft. Running gear - 4 toughened cast steel flanged wheels, 12 in. dia. for I cu. yd. wagons and 15 in. dia. for 2cu. yd. wagons; pressed fast on to mild steel axles; outside journals. Axleboxes - Hudson 'FARO" type with ball bearings and rust-less metallic grease seals. Springs - Rubber cushion pads are supplied with the axleboxes. Couplings - Provision is made for link couplings at the front and rear of each wagon. Body catch - The body catch can be operated from either side of the wagon and ensures discharge away from the operator. Automatically locks when the body returns to the upright position. Weights Average weight of 1 cu yd Type A wagon - 835 lb. Average weight of 2 cu yd Type B wagon - 2,120 lb. Overall dimensions (Type A): - Length - 6 ft. 1½ in. Width - 4 ft. 11½ in.
