For the first 100 years that railroads were the prime mover of freight and passengers, boiling water in a boiler was the only means of motive power. By the 1960s, steam engines were largely gone from the rails, replaced by diesel power.

Puffing Billy is the world's oldest surviving steam locomotive, constructed in 1813–1814 by colliery viewer William Hedley, enginewright Jonathan Forster and blacksmith Timothy Hackworth for Christopher Blackett, the owner of Wylam Colliery near Newcastle upon Tyne, in the United Kingdom.
There are two technologies that separate modern steam locomotives from traditional locomotives: the implementation of the Gas Producer Combustion System (GPCS) in place of conventional steam locomotive combustion (which works in tandem with a high efficiency exhaust) and the use of a modern and much more effective ...
The old steam engines were usually run well below 40MPH due to problems with maintaining the tracks-- but could go much faster. I seem to recall a 45 mile run before 1900 in which a locomotive pulled a train at better than 65MPH... (Stanley Steamer cars were known to exceed 75MPH). 3.
Steam engines lasted well into the late 1950s on major American railroads, and in isolated cases into the middle 1960s on small common carrier roads. The last steam locomotive fleet in everyday use (i.e. not a restored fleet) was retired in the late 1970s.
A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.
Twenty-five Big Boy locomotives were built for Union Pacific to haul freight over the steep grade of the Wasatch Mountain Range in Utah during World War II. Eight were preserved after the locomotive was retired six decades ago, but only Big Boy No.4014 is still in operation.
The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747.
Air pollutionSteam trains were indeed faster than wagons, and steam ships faster and stronger than sailing ships. But the smoke they sent into the air polluted the air. Then diesel and electric trains came, and they were somewhat cleaner.
Similarly, in France, about 45% of the railway network is not electrified and there are more than 1,200 diesel trains. In India, which has the world's third largest railway network, 37% of the trains are pulled by diesel locomotives, Vaishnaw had told Rajya Sabha in December 2021. That's roughly 5,000 trains a day.
