To support the main business and provide a complete service to the customer, Robert Hudson supplied almost any related equipment. To achieve this range of products, many of the items were bought in. A typical example of this is weighbridges that were supplied by Denison's Foundry in Leeds.
Wagons
In 1875 Hudson patented the "triple centre" side tipping truck. This truck is of triangular section and has support frames at each end with three pivot points. The centre pivot being the normal rest position whilst the two outer pivots being used for tipping left or right. This arrangement allows the contents to be easily removed by one man without overturning the truck. Another innovation that Hudson introduced was the use of hydraulic machinery to form pressed steel components. The use of corrugation as part of the pressing process also helped to provide a strong body with thinner gauge steel. This combination provided a competitive advantage that contributed to Hudson's success.
Types of wagon produced by Robert Hudson Ltd were many and varied. Principal types included the tipping wagon mentioned above, in all gauges up to standard gauge, and typified by the "Rugga" tipping wagon, introduced in the 1930s to replace the earlier Victory skip wagons. Rugga wagons were primarily produced for and gauges, but like all Hudson products, could be manufactured to any gauge required. Rugga wagons were built in a range of sizes from the smallest at 13.5 cuft up to a huge 54 cuft. Variations included "light" versions for hand-tramming, medium duty for light work using locomotives, through to heavy duty for more extreme conditions and materials such as rocks. The heavier duty versions had thicker metal bodies, double ball bearing races in each axlebox and usually a central stiffening girder. Hudson boasted that " at any time several thousand Rugga wagons are in stock, for immediate delivery"
Another principal product was mine tubs, found in almost all UK collieries and similar operations elsewhere in the British Empire. Again, versions included different capacities, hand, winding engine or loco haulage, as well as being manufactured in all gauges.
Other wagon types included "U" skips for tunnelling, Granby cars,[9] flat wagons, cane cars for sugar cane, carriages, kiln cars, timber bolsters, box cars. hopper wagons, anode and cathode cars, bottom discharge wagons, ammunition wagons, concrete pouring skip wagons.[10]
Track and track components
Hudson supplied a vast array of track components, from the rail in all of its multitude of sections and weights per yard, through to individual bolts, nuts and washers. The smallest rail section is usually found around 12 lb/yard, while the heaviest rail shown in the 1957 catalogue is 60 lb/yard.[2] With the rail, Hudson supplied fishplates and bolts to suit, spikes for wooden rails, chairs and screws for wooden rails, metal sleepers of various sections, including clips and bolts.[11]
Specialist track components such as turntables ,[12] switches (points), point levers, mine transfer cars, temporary turnouts, easy turnouts, rerailing ramps, could all be found in the catalogues. And the tools required to build and maintain the track, including gauges, rail benders, rail cutters, rail drills
Steam locomotives
In 1911 Robert Hudson entered into an agreement with Hudswell Clarke for the manufacture of narrow gauge locomotives, an agreement which ran from 1911 through 1929.[1] This arrangement produced 16 standardised designs, designated A to Q, which ranged from 5 hp engines to 55 hp models. The designs were sufficiently flexible to allow for the various track gauges in use. Over the years, 188 locomotives were supplied to these designs.
Petrol and diesel locomotives
Hudsons also realised the advantages of the internal combustion locomotive and the 1915 catalogue offered a range of five petrol locomotive supplied by Avonside Engine Company of Bristol.
When the Fordson petrol tractor became widely available in the 1920s Hudsons adapted this unit to make a simple locomotive. The locomotive used a four-wheeled cast chassis to which a roller chain drive connected to the tractor axle. The tractor gearbox had three forward speeds but only one reverse gear, which clearly was a limitation for a locomotive that has to operate bi-directionally. Only a few of these machines were constructed but fortunately a gauge, 1928 model is preserved at the Armley Mills Industrial Museum, Leeds. The oldest working Hudson Hunslet engine '1944', (built in 1939) has just been restored, complete with her original Ailsa Craig 20 hp engine, and is preserved at the Old Kiln Light Railway, Tilford, Surrey.
The manufacture of internal combustion locomotives was not pursued and Hudsons often supplied Avonside Engine Company or Kerr Stuart units to their customers. When the Hunslet Engine Company took over these designs it was only logical that Hudsons would form a partnership with Hunslet.[13]
Mining equipment
Hudson was a major player in setting the standards for coal haulage. In the 1930s the introduction of practical locomotive haulage in coal mines demanded better wagons than the traditional plain bearing designs. Hudson introduced new designs with pressed steel corrugated bodies with roller bearing wheels. This style of vehicle was ultimately adopted by the National Coal Board as its standard coal haulage vehicle.
Catalogue
The catalogue issued in 1957,[2] illustrates the vast range of products and consisted of nine separate books:-
Springs. Lubrication. Brakes and Braking. Buffers and Coupling. Parts and Attachments for Wagons. Special Steels.
- Section A – Track and Track Accessories. Turnouts and Switches and Crossings. Turntables and Easy Turnouts. Platelayers tools.
- Section B – Contractors' and Quarry type Tipping Wagons and Miscellaneous Light Tipping Wagons.
- Section C – Double Side Tipping Wagons, Double End Tipping Wagons, Tippler Trucks, and Box Cars for Mining and Tunnelling.
- Section D – Mine Cars Cane, Sisal and Fruit Cars. Trailers. Platform and Tank Wagons. Brick Cars and Industrial Trucks. Logging Bogies and Estate Cars.
Road vehicles
In the 1960s, Hudson introduced a range of road vehicles. The "Leedsall" dumper truck was first produced in 1966.[14] This was followed by the "Kiwi" mobile yardcrane, the "Timser" low loading trailer and the "Frontomatic" concrete truckmixer. These developments initially provided replacement work for the declining orders for railway equipment and to consolidate this, a Contractor's Equipment division was formed in 1964. In 1968 a separate building was opened on the main Wakefield-Bradford Road with showrooms and land for demonstration purposes. With the demise of the Gildersome works the company became a sales and service organisation for construction plant and machinery e.g. Ford, Barford, Kubota.
In 1981 the much reduced Raletrux business relocated to Mill Green in the Wortley district of Leeds, however, the declining railway business finally took its toll in 1984 when the company was liquidated. The remaining plant, machinery, stores and equipment were auctioned on 31 January 1985 at the Mill Green works. The goodwill passed to NEI Becorit and ultimately to Clayton Equipment, based in Derby, who are still very active in the narrow gauge railway industry and using the Robert Hudson name in their marketing.
