During the past 20 years, a solid rolled one-piece, one wear wheel of which the tire is an integral part, has been developed and has been standardized for British Railways. With the increase in capacity of modern all-steel mineral wagons to 16 tons, the laden weight of which is 24 tons axles as used for the tank wagons referred to, with 9-in. times 4.5 in. journals and 5.75 in. dia. wheel seats, were adopted, the stress being somewhat lower, namely, 22,700 lb. per sq. in. behind the wheel seat. After extensive trials, axlebox dust shields, which had always given much trouble, were dispensed with. This design has been adopted by British Railways as the standard for cast-iron axleboxes. A uniform standard van was adopted with hinged doors, incorporating pressed-steel ends, having 5/8-in. thick softwood boards or other suitable materials for the sides. The vehicles will be mounted on standard steel underframes, 17 feet 6 inches long with a 10-feet wheelbase, generally fitted with vacuum brake for fast freight working, having a load capacity of 12 tons, with the latest improvement in drawgear, axleboxes, and other fittings.
