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 ...
The balance lever coupling, also central buffer coupling with two screw coupling, is a coupler commonly used on narrow gauge railroads with tight curves. By swapping the pulling and pushing devices, the standard screw coupling used on standard gauge railroads became a center buffer coupling with one screw coupling on each side of the buffer.
The N prefix is for "narrow" gauge, and the suffix indicating that it is a bogie wagon much like NUU, NTT, etc. above. However, unlike those examples, it is likely that the Victorian Railways would have retained the "NNN" code instead of simplifying to "NN", because there was already a broad-gauge ballast vehicle of that classification.

However, owing to a boom in patronage, and the Kerang rail accident, from late September 2007 they were re-introduced to service as a dedicated train set on the Geelong line, to replace set N7. [2] That set was finally withdrawn from service on 9 August 2010, running the 7:47am service from South Geelong to Southern Cross. All of V/Line's ...
This article outlines the history and types of passenger rolling stock and guards vans on the narrow-gauge lines of the Victorian Railways in Australia. The types were constructed in parallel with very similar designs. All passenger carriages operating under the Victorian Railways were painted a deep red, with black underframes and white lettering. In the early preservation era, vehicles ...
a throttle lever or regulator, which controls the amount of steam entering the cylinders [3]: 75 : 82 a reversing lever or (US term) Johnson bar, which controls the timing of the admission of steam into the locomotive's cylinders. [3]: 65 This is required for two purposes. One is to reverse the locomotive's direction, e.g. when shunting.
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 ...
At the end of 1996, vans CP292 and CP294 were converted to include head-end-power generators in the west end, and recoded to PCP. The maximum goods load was reduced from ten tonnes to six, and the conversion included repainting of the existing scheme including the tail-end stripe. In 1998 the two PCP vans were repainted.
