Why did diesel replace steam power?

Diesel locomotives were generally more powerful than the steam locomotives that came before them. They were also less polluting, and they did not have to stop to pick up water. Diesel-powered trains are used worldwide, especially on less busy routes where it would be too expensive to electrify the lines.

There the economic edge ended, however, as diesels were far cheaper to operate. Fuel costs were less, for openers, but that was just the beginning. Typically, steam spent far too little time on the road and far too much in the shops and engine terminals being serviced and inspected.

Diesel engines are much more efficient than steam engines, but the combustion in the steam engine's firebox can be more carefully controlled and, so, possibly produce less of the types of pollution caused by imperfect combustion.

Steam engines CAN be more powerful than diesels. Steam engine have been built with 7000–8000 hp. They tend to be very heavy and very complicated with multiple driving axle articulated trucks.

Coal fired steam locomotives do produce a lot of CO2 emissions but also aerosols which has a cooling effect (global dimming), which cancels out some of the warming produced by CO2. Diesel locos probably produce less CO2 but also less aerosols that would cancel out the CO2.

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.

True, there is little or no chance of steam trains replacing electric and diesel trains on our modern rail network. But if steam remains history, it is an unusually active and extensive variety of history. Steam has made an impressive comeback under the guise of heritage, to become an enormous national asset.

Diesel locomotive engines are a major contributor to air pollution. The culprits are NOx SO2. Both are readily produced by diesel locomotives and both cause an array of health and environmental problems.

But when the price of oil started to fall in the 1960s, and so-called 'dieselisation' began, it marked the beginning of the end for steam. Diesel engines were faster, easier to maintain, and cleaner.
