Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines , while also being much simpler, more reliable, smaller and lighter all at the same time.
The final class of 2-6-6-4s was the Norfolk and Western Railway's A class, built starting in 1936. 43 were built until 1950 but were operated until 1959 to prepare the ending of steam power. The powerful 2-6-6-4s were capable of more than 5,000 drawbar horsepower at 45 mph (72 km/h) and could reach 70 mph (110 km/h), while pulling heavy coal ...
The book depicts American history throughout the 1960s. The book's title refers to a fragile but stable social fabric that was present in the United States in the 1950s, held together by racial segregation, an expanding military industrial complex and repression of sexual rights; a social order that would be shattered in the 1960s.

The last engines of the classes 23.10, 65.10 and 50.40 were retired in the late 1970s, with some units older than 25 years. Some of the narrow-gauge locomotives are still in service for tourism purposes. Later, during the early 1960s, the DR developed a way to reconstruct older locomotives to conform with
A steam shovel is a large steam-powered excavating machine designed for lifting and moving material such as rock and soil. It is the earliest type of power shovel or excavator. [citation needed] Steam shovels played a major role in public works in the 19th and early 20th century, being key to the construction of railroads and the Panama Canal.
During the 1950s, N&W rebuilt its W Class 2-8-0 Consolidations into Shop Co W6 0-8-0Ts. In 1960, the N&W became the last major railroad in the United States to abandon steam locomotives for diesel-electric motive power. The Roanoke Shops continued to build and repair rolling stock until 2020 when Norfolk Southern closed them, ending 139 years ...
During the Industrial Revolution, steam engines started to replace water and wind power, and eventually became the dominant source of power in the late 19th century and remaining so into the early decades of the 20th century, when the more efficient steam turbine and the internal combustion engine resulted in the rapid replacement of the steam ...
