The steam locomotives of British Railways were used by British Railways over the period 1948–1968. The vast majority of these were inherited from its four constituent companies, the " Big Four ". In addition, BR built 2,537 steam locomotives in the period 1948–1960, 1,538 to pre-nationalisation designs and 999 to its own standard designs.
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 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
The A, J, and Y6 locomotives, designed, built and maintained by NW personnel, brought the company industry-wide fame for its excellence in steam power. The N&W's commitment to steam power was due in part to its investment in the manufacturing capacity and human resources to build and operate steam locomotives, and partially due to the major ...
For the last decade of Pennsy's existence (1960s), the Pennsy was ordering 4-axle power, buying Alco's 'Century' series locomotives, newcomer General Electric (GE) U25Bs, and EMD GP30s and GP35s. But by 1965, the Pennsy turned exclusively to 6-axle power, buying Alco's C628 and C630 , GE's U25C , U28C , and U30C , and EMD's SD35 , SD40, and SD45.
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 ...
Train enthusiasts and history buffs alike will soon have a new Southeast Asian destination, as Vietnam prepares to unveil a revamped pair of vintage steam locomotives from the 1960s.
The name Tom Thumb is forever associated with the B&O, as the first steam locomotive built in the United States for an American railroad. It was built strictly as a demonstrator, but it was succeeded by a series of similar locomotives (the " Grasshoppers " and the "Crabs") designed by Ross Winans , the first head of motive power on the railroad ...
