Sierra Railway #3 on the P&AC. No. 3 is a 4-6-0 Ten-Wheeler steam locomotive built by the Rogers Locomotive and Machine Works of Paterson, New Jersey.Construction of the locomotive was completed on March 26, 1891, and was given Rogers construction number 4493.
Many steam locomotive toys have been made, and railway modelling is a popular hobby. Steam locomotives are often portrayed in fictional works, notably The Railway Series by the Rev W. V. Awdry, The Little Engine That Could by Watty Piper, The Polar Express by Chris Van Allsburg, and the Hogwarts Express from J.K. Rowling's Harry
The throttle is not the only control that can limit the locomotive's power output: during steady-state running of most locomotives, the throttle is usually set wide open and the power output is controlled by moving the reversing lever (2) closer to its mid-point ("reducing the cut-off") to limit the amount of steam admitted to the cylinders.
The Union Pacific Big Boy is a type of simple articulated 4-8-8-4 steam locomotive manufactured by the American Locomotive Company (ALCO) between 1941 and 1944 and operated by the Union Pacific Railroad in revenue service until 1962.
It was the last new steam locomotive to be delivered to the Nickel Plate Road, and alongside L&N 1991, another 2-8-4 for the Louisville and Nashville, is the last of 36 steam engines completed by Lima-Hamilton from 1947 to 1949, and the final 2-8-4 locomotive on standard gauge completed in the world.
The way the valve controlled the steam entering and leaving the cylinder was known as steam distribution and shown by the shape of the indicator diagram. What happened to the steam inside the cylinder was assessed separately from what happened in the boiler and how much friction the moving machinery had to cope with.
Some locomotives are designed specifically to work steep grade railways, and feature extensive additional braking mechanisms and sometimes rack and pinion. Steam locomotives built for steep rack and pinion railways frequently have the boiler tilted relative to the locomotive frame, so that the boiler remains roughly level on steep grades.
An early working model of a steam rail locomotive was designed and constructed by steamboat pioneer John Fitch in the United States probably during the 1780s or 1790s. [40] His steam locomotive used interior bladed wheels [clarification needed] guided by rails or tracks. Union Pacific 844, an "FEF-3" 4-8-4 "Northern" type steam locomotive
