A drawing design of the N&W class J locomotive. After the outbreak of World War II, the Norfolk and Western Railway's (N&W) mechanical engineering team developed a new locomotive—the streamlined class J 4-8-4 Northern—to handle rising mainline passenger traffic over the Blue Ridge Mountains, especially on steep grades in Virginia and West Virginia.
An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
The MOW crew had to disconnect the locomotive from its tender and rerail it one set of wheels at a time. [9] On the afternoon of January 26, No. 611 was finally back on the rails and towed to Williamson for inspection. [5] [9] The locomotive's skirting panels, running boards, valve gear parts, and other appliance parts were torn off from its ...
An equalising system links not only the driving-wheel axles but also the trailing and/or leading truck axle(s). [3]: 32 [5] [6]: 425 Leaf springs Main suspension springs for the locomotive. Each driving wheel supports its share of the locomotive's weight via leaf springs that connect the axle's journal box / axle box (40) to the frame.
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. [1] Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country.
Nos. 611 to 617 were a larger development of the earlier 601 class locomotives. They were fitted with a Deutz F/A8L 714 engine of 120 kilowatts (160 hp), with Voith hydraulic transmission, weighed 22 tonnes (22 long tons; 24 short tons) and had a maximum speed of 42 kilometres per hour (26 mph).
Steel tire on a steam locomotive's driving wheel is heated with gas flames to expand and loosen it so it may be slipped over the wheel.. The steel wheel of a steam locomotive and other older types of rolling stock were usually fitted with a steel tire (American English) or tyre (in British English, Australian English and others) to provide a replaceable wearing element on a costly wheel.
