The End of an Era: Transition from Steam to Modern Locomotives
Written on
Chapter 1: The Rise of Diesel Technology
In the early 20th century, a significant shift in locomotive technology began. In 1906, pioneers Rudolph Diesel, Adolf Klose, and Gebruder Sulzer established Diesel-Sulzer-Klose GmbH, focusing on diesel-powered locomotives. Sulzer was instrumental in this venture, having already been involved in diesel engine production since 1898.
The inaugural diesel locomotive commenced operations in the summer of 1912. However, its progress was hindered by technical issues in 1913, followed by the onset of World War I in 1914, which stalled further advancements. This locomotive was quite impressive, weighing 95 tons with a power output of 883 kW and a maximum speed of 62 mph. But for now, we will set aside the story of diesel locomotives, as we delve into the decline of steam engines, which were once heralded as revolutionary in transportation.
Beginning in the 1920s, steam engines gradually faced retirement as diesel and electric alternatives gained prominence. This transition did not occur uniformly worldwide; different regions adopted these new technologies at varying rates. This article aims to chronicle the timeline of steam locomotive decommissioning in mainline services, starting with North and South America and progressing to other global regions.
Section 1.1: North and South America
United States
The last steam-powered standard-gauge freight service by a Class 1 railroad occurred on October 11, 1962, on the isolated Leadville branch of the Colorado and Southern (Burlington Route) with a 2–8–0 locomotive numbered 641. Narrow-gauge steam continued to serve freight routes operated by the Denver and Rio Grande Western until December 6, 1968.
Interestingly, the Union Pacific Railroad stands out as the only Class I railroad in the United States to maintain an operational steam locomotive, Union Pacific 844, throughout its transition to diesel. Meanwhile, smaller rail companies continued to use steam engines into the 1960s and beyond. Notably, the Northwestern Steel and Wire mill in Sterling, Illinois, operated steam locomotives until December 1980, while the Crab Orchard and Egyptian Railway held out until September 1986.
Out of over 160,000 steam locomotives built in the United States between 1830 and 1950, approximately 1,800 remain, with a small fraction still operational at museums, tourist railroads, or mainline excursions.
Mexico
In Mexico, standard gauge steam locomotives, specifically 4–8–4 models produced in 1946, were used for freight transport between Mexico City and Irapuato until 1968. A short line in Sinaloa reportedly operated steam locomotives as late as August 1987.

Section 1.2: International Perspectives
Britain
The last steam locomotive constructed for British Railways was the 92220 Evening Star, completed in March 1960. The final steam-hauled service trains operated on British Railways on August 11, 1968. However, steam locomotives continued to be utilized in various industries into the 1980s. By June 1975, steam was still regularly in use at 41 locations, with many more engines held in reserve.
Many preserved steam locomotives now operate on volunteer-run heritage railway lines in the UK, with some regularly appearing on the national rail network for special excursions.
Germany
In Germany, standard steam locomotives constructed in the 1920s and 1930s remain prevalent. The Deutsche Bundesbahn (DB) began phasing out steam-hauled trains in 1960, yet around 5,000 engines remained operational. The last steam express train ran in 1975, marking the end of an era for steam locomotion in West Germany.

Chapter 2: Global Transition Away from Steam
Russia and Asia
The last steam locomotive in the Soviet Union was built in 1956. By the 1960s, most steam engines had been replaced by diesel and electric counterparts, although some remained operational in Siberia until the mid-1980s. In China, steam locomotives continued to be built until the late 20th century, with the last mainline steam service officially ceasing on the Jitong line at the end of 2005.
Conclusion
Despite the decline of steam locomotives in many regions, a remarkable number of them have been preserved and continue to operate in various capacities around the world. I find great joy in exploring the history, watching related films, and admiring images of these iconic machines.
