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.
A skidder is any type of heavy vehicle used in a logging operation for pulling cut trees out of a forest in a process called "skidding", in which the logs are transported from the cutting site to a landing. There they are loaded onto trucks (or in times past, railroad cars or flumes), and sent to the mill. One exception is that in the early ...

The diagram from Beard's 1897 coupler patent [1]. Janney couplers were first patented in 1873 by Eli H. Janney (U.S. patent 138,405). [2] [3] Andrew Jackson Beard was amongst various inventors that made a multitude of improvements to the knuckle coupler; [1] Beard's patents were U.S. patent 594,059 granted 23 November 1897, which then sold for approximately $50,000, and U.S. patent 624,901 ...
Narrow gauge flat wagons, 750 mm (2 ft 5 + 1 ⁄ 2 in).Note the single buffer with a hook on the right side and a chain on the other. On some narrow-gauge lines in Europe, and on the Paris Metro, a simplified version of the loose-coupler is used, consisting of a single central buffer with a chain underneath.
Six units, accompanied by matching trailing car sets, were manufactured exclusively for the Southern Railway. Two were later sold to the Georgia and Florida Railroad and Georgia Northern Railway as maintenance cars. The remaining four OP800s were scrapped in 1955; selected parts were retained for maintenance use on other SR F-M motive power.
The log was taken either to a mill or to a "landing" where it would be transferred for onward shipment by railroad, road or river – either send down a flume, loaded onto boats, or floated directly in the water, often becoming part of a large log raft or "boom". Later, a "haulback" drum was added to the donkey, where a smaller cable could be ...
Span bolsters can be seen at both ends of this diagram of the 14"/50 caliber railway gun. A span bolster, in rail terminology, is a beam or frame used to link two trucks or bogies so that they can be articulated together and be joined to the locomotive or railroad car at one rotating mounting point. In effect, they make one "super-truck" out of ...
