His first locomotive was the Onward, a 3 ft (914 mm) gauge 0-4-4T completed 1 July 1872. Onward would enter service on the American Fork Railroad shortly afterwards before being moved to the Eureka and Palisade Railroad in 1873. [3] Onward was a largely successful engine, but certain design elements proved troublesome. Bolts worked loose ...
The valve gear, actuated by connection to the driving wheels, ensures that steam is delivered to the piston with precision. Types are slide valves, piston valves or poppet valves. [2] [3]: 62 Valve chest / Steam chest Valve chamber next to the cylinder (24) containing passageways to distribute steam to the cylinders. [6]: 41 [3]: 75 Firebox
Tremont and Gulf Railroad No. 30 is a preserved class 30 2-8-2 "Mikado" steam locomotive built by the Baldwin Locomotive Works in 1917 for the Tremont and Gulf Railroad. It was used by the T&G for hauling freight trains in branch lines throughout the state of Louisiana until 1954, when it was sold to the Magma Arizona Railroad and renumbered 7.
When a train has made a full brake application due to adverse event, or has lost its train air due to a defective valve (a "kicker"), or a broken air line or train separation. The train crew will normally declare that they are "in emergency" over the train radio, thus warning other trains and the dispatcher that there is a problem. [101] [102]
They were connected to 81-inch (2,057 mm) driving wheels by a variety of valve gear: most had Stephenson valve gear and 11-inch (279 mm) piston valves; No. 1026 was fitted up with Youngs rotary valves and valve gear in 1903, [1] but later reverted to Stephensons valve gear.

When the Denver & Rio Grande split with the Denver & Rio Grande Western Railway, all of the Grant built locomotives including 223 were retained by the Colorado railroad. [11] The rapid standard gauging of the former D&RGW.Ry mainline via successor Rio Grande Western in the following years cut off direct narrow gauge interchange from Colorado to ...
In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. [1] [2] Elementary particles whose interactions are described by a gauge theory interact with each other by the exchange of gauge bosons, usually as virtual particles. Photons, W and Z bosons, and gluons are gauge
