. Whereas the benefit of replacing steam traction is indisputable, there is some dispute as to whether it is best replaced by dieselisation or electrification. Electrification has a high initial capital cost but the operating costs are lower. The overall savings depend on the effect of the investment cost compared with the savings due to lower operational and maintenance costs and the influence of better acceleration and tractive effort on railroad throughput. These are obviously different for e.g. urban networks and very long-distance networks with low frequencies. However, many railway commentators are increasingly suggesting that the ability of railways to operate with electricity not produced from fossil fuels may offer a decisive advantage over diesel power.

Advantages of diesel in rail transport

Dieselisation took place largely because of the reduction in operating costs it allowed. Steam locomotives require large pools of labour to clean, load, maintain and run. They also require extensive service, coaling and watering facilities. Diesel locomotives require significantly less time and labour to operate and maintain.

Diesel engines have thermal efficiency above 40% compared to about 6% for single expansion steam. Diesel engines also have higher power-to-weight ratios.

Steam engines caused more hammer blow

In North America, railroads looked to cut costs in the face of stiff competition from trucks, planes and automobiles. Railroads in America at this time also had an image problem, viewed as archaic, a fact that was re-enforced in the war when retired equipment was pressed into service. This left a lasting impression on millions of servicemen who were delayed for days in often obsolete, uncomfortable cars in obscure locations. Locomotive size also became an issue, as steam engines became so big in the 1940s that the cylinder and boiler dimensions were pushing the limits that the loading gauge

es became so big that firing a steam locomotive became an extremely difficult job without the aid of mechanical stokers.

Unlike steam locomotives, diesel locomotives are scalable, with the added benefit of multiple unit (MU) operation (additional locomotives coupled together under the control of a single crew). Use of MU allows longer trains, exploiting economies of scale. Diesels can also operate for greater periods of time before needing servicing, so small division points were closed as operating districts were lengthened .

Diesels slowly gained the advantage. Weighing against the cost of, and inertia against, replacing the large investment that railroads had in existing steam power was the dramatic increase in efficiency of the diesel: The diesel locomotive can be operated by a single person, with no need of a fireman to shovel coal. Also, diesels use much less fuel and no manpower when idling, something locomotives often do. Diesels can be parked running for days unattended, whereas steam engines must be constantly tended to if not completely shut down. Bringing a steam engine boiler up to operating temperature

 is often regarded as both an art and science, requiring much training and experience. A diesel starts and shuts down just like an automobile. Diesels pro-rate their fuel usage to the length of trains, which a steam engine cannot do. General Motors signed proprietary contracts with the major railroads, who were replacing their worn out wartime equipment, with diesels. With the GM contracts came articles that GM would supply training, facilities and maintenance, while the railroads would scrap their steam engines and remove them from competition. Due to the modern advantages of diesel locomotives, railroads in North America had retired 90% of their steam locomotives by the mid 1950s. Also, major cities and their railyards became unhappy neighbors in post-war America. People were no longer content to endure the mammoth amounts of soot and smoke that coal burning steam engines produced. Early diesels, while dirty by today's standards, were a gigantic improvement in air pollution over steam.

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, primarily for yard duties such as switching. The last steam locomotive fleet in everyday use (i.e. not a restored fleet) was retired in the late 1970s. Now they are only found in historical and sightseeing roles, where the steam engine is once again the star of the show. Retired steam engines, many of which were quite new when made obsolete, often did find a second life in developing nations due to their cheap labor for maintenance and crewing, ready supplies of coal, and lack of environmental concern.


With the exception of the United Kingdom, the trend in Europe was to replace steam traction in the main lines with electric traction. Diesels were used as an interim solution during electrification and as a permanent solution for side lines with less traffic and as switchers. Electrification is nowadays widespread in Europe. Even in sparsely populated large countries (Finland, Sweden) electrification has proven to be more economical than diesels.

The reputation of diesel benefited from memories of World War II, when military vehicles – especially tanks – using diesel were less prone to burst into flames when hit than their petrol-engined counterparts.

Soviet Union

The major disadvantage of the steam locomotive - large water consumption and thus small range from loading to loading - was particularly important in the Soviet Union, especially in steppes and deserts of South Siberia, Kazakhstan and Central Asia where water can be scarce. This spurred work on diesel locomotives in late 1930s, when several machines were delivered and tested.

Nevertheless, the diesel had much less power than the steam locomotive, the issue at the time was the difficulty of producing an engine of large enough scale to power a locomotive.

This was solved after the adoption of an American marine diesel from the Liberty

The power of the TE3 was equivalent to that of the largest steam engines at the time and given all of the other numerous advantages of the diesel engine, it was decided to abandon steam locomotives completely.

All types of steam locomotives in the USSR stopped production in 1956.

Latin America and Asia

Latin American countries employed their steam locomotives until the late 1960s and 1970s. Some nations, those with less oil reserves, such as India, China and South Africa used steam until the 1980s and 1990s. China and India have now large electrification programs.
Russia or the Soviet Union electrified, and steam service ended in the 1970s.
Asian nations used steam until the 1970s when those nations modernised.
