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.
DB DMU 611 508 in Nuremberg. Class 611, successor to the DB Class 610, was developed using tilting systems from German military technology in favour of the Hydraulic Fiat systems used by its predecessor [citation needed] Because of environmental concerns over the potential hazards of leaking hydraulic fluid an electrically actuated option based on equipment used to keep the guns of tanks level ...
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 ...
[2] [3] When the train was running at 58 mph (93 km/h) near the Great Dismal Swamp in Suffolk, Virginia, two of the passenger cars struck a faulty switch on the main line derailing them and the other 12 passenger cars with them. [4] The locomotive, first six cars, and last two cars stayed on the rails undamaged.
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.
The Pennsylvania Railroad's Q2 class were the only locomotives ever to use this arrangement. These were duplex locomotives, in which both sets of driving wheels were mounted in a common, rigid locomotive frame. This locomotive design was a further development of the highly successful 2-10-4.
A Boxpok is a steam locomotive wheel that gains its strength through being made of a number of box sections rather than having traditional solid spokes (the name is a variation on "box-spoke"). Being hollow, they allow better counterbalancing and stability than conventional drivers, which is important for fast locomotives.
The Canadian Pacific Railway built two classes of 4-4-4 "Jubilee" locomotives. Both were semi-streamlined, in a similar fashion to the 4-6-4 " Royal Hudson " and 2-10-4 " Selkirk " locomotives. The F2a was styled after the Milwaukee Road "Hiawatha" 4-4-2 "Atlantic", but with a four-wheel trailing truck to support a longer firebox.
