The diagram, which is not to scale, is a composite of various designs in the late steam era. Some components shown are not the same as, or are not present, on some locomotives – for example, on smaller or articulated types.
Diagram of Priestman oil engine from The Steam engine and gas and oil engines (1900) by John Perry Petrol–electric Weitzer railmotor, first 1903, series 1906. The earliest recorded example of the use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman, which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as ...
Animated diagram of Deltic engine Cylinder firing order of the 18 cylinder Napier Deltic diesel engine: The grid represents triangular cylinder arrangement (banks A, B, C) and rows 1 to 6 The Napier Deltic engine is a British opposed-piston valveless , supercharged uniflow scavenged , two-stroke diesel engine used in marine and locomotive ...
Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven.
The colours dark and light green represent wet and dry steam respectively. The colours orange and yellow represent hot and cooler exhaust gas respectively. In the diagram, three small-diameter orange/yellow empty firetubes are indicated to the bottom, with two larger diameter orange/yellow firetubes to the top that contain the superheater elements.
Diagram showing lap and lead and their relation to valve travel. When on the move, a steam locomotive requires steam to enter the cylinder at precise times relative to the piston's position. [3] This entails controlling the admission and exhaust of steam to and from the cylinders with a valve linked to the motion of the piston. [3]
A Climax locomotive is a type of geared steam locomotive built by the Climax Manufacturing Company (later renamed to the Climax Locomotive Works), of Corry, Pennsylvania. These had two steam cylinders attached to a transmission located under the center of the boiler, which sent power to driveshafts running to the front and rear trucks .
The cylinders on a Shay locomotive. There are many other variations, e.g. geared steam locomotives which may have only one cylinder. The only conventional steam locomotive with one cylinder that is known is the Nielson One-Cylinder Locomotive. [3]
