retirement in buenos aires

Beginning in 1917, steam locomotives were gradually retired and replaced by diesel and electric locomotives. The timeframe of this process varied by country.
Railfan & Railroad stated in 2022 that "the only places on earth to see steam locomotives in revenue freight service are small switching operations in China, North Korea and Bosnia," but that these were "sporadic at best." While the use of steam locomotives in mainline service has largely come to an end, preserved steam trains are still in regular use around the world.
