The R type carriages were a series of locomotive-hauled carriages proposed to be built for the Victorian country rail network in the early and mid 1980s.. Early plans indicated a build of at least six four-carriage sets for high speed services on the Albury, Bairnsdale, Mildura and Swan Hill lines.
A turntable for the Central Railroad of New Jersey. Turnplates at the Park Lane goods station of the Liverpool and Manchester Railway in 1831. Early wagonways were industrial railways for transporting goods—initially bulky and heavy items, particularly mined stone, ores and coal—from one point to another, most often to a dockside to be loaded onto ships.

[3] [4] Robertson then relocated the company to produce his screws in Milton, Ontario, the following year after the town had given a $10,000 loan for the factory's local establishment. [ 3 ] [ 4 ] [ 6 ] The new location also provided incentives to Robertson's factory such as direct roads to the plant, reduced water rates, a sewage disposal ...
The valve gear operation combines two motions; one is the primary lead motion which is imparted at the bottom of the combination lever (12). The secondary is the directional/amplitude motion which is imparted at the top. Consider that the driver has adjusted the reversing lever such that the die block is at mid-gear. In this position the ...
Henry Maudslay's early screw-cutting lathes of circa 1797 and 1800.. A screw-cutting lathe is a machine (specifically, a lathe) capable of cutting very accurate screw threads via single-point screw-cutting, which is the process of guiding the linear motion of the tool bit in a precisely known ratio to the rotating motion of the workpiece.
A compound machine is a machine formed from a set of simple machines connected in series with the output force of one providing the input force to the next. For example, a bench vise consists of a lever (the vise's handle) in series with a screw, and a simple gear train consists of a number of gears (wheels and axles) connected in series.
To prevent accidents, operating a set of points requires pulling the actual lever for the points and a secondary check lever. The points are then moved by a hydraulic motor. This type of power frame has the disadvantage of a relatively low distance between points and signal box (approximately 200–250 m) and a slow operating speed.
In 1933, two A 2 class locomotives set a haulage record for Victorian Railways when they headed a 75-truck 1,598-long-ton (1,624 t) wheat train from Benalla to Seymour. [ 18 ] Pairs of A 2 class engines were regularly worked on the Melbourne-Ararat and Ararat-Serviceton portions of The Overland ; common candidates included A 2 940, A 2 942, A 2 ...
