context_page_description: Robert Hudson Ltd was a major international supplier of light railway materials, based in Gildersome, near Leeds, England. The name was later changed to Robert Hudson Ltd.
context_section_description: 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 2 ft (610 mm) and 600 mm (1 ft 11 ⁵⁄₈ in) gauges, but like all Hudson products, could be manufactured to any gauge required. Although it is not often appreciated, Rugga wagons were built in a range of sizes from the smallest at 13.5 cu ft or 0.50 cu yd or 0.38 m³ up to a huge 54 cu ft or 2.0 cu yd or 1.5 m³. 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 s 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, 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.
