Even if they were more fuel efficient, they wouldn't make a comeback in their original form. The steam locomotives required way more maintenance than the diesel locomotives, and way more manpower to keep them operating and repaired which is why they were replaced by diesel locomotives.
When Englishman Richard Trevithick launched the first practical steam locomotive in 1804, it averaged less than 10 mph. Today, several high-speed rail lines are regularly travelling 30 times as fast.
Steam engines, as a mechanical source of power, do NOT cause pollution. However the steam generated in a boiler may be heated by an energy source that does cause pollution. There are several sources of energy that can be used to make steam, both for railway and stationery power applications.
Steam wasn't systematically phased out in the U.S. until the 1960s. Today, there is still one steam locomotive operating on a Class I railroad in the U.S., the Union Pacific 844. For the most part, though, the U.S. and the rest of the world have converted to electric and diesel.
Steam passes to the piston valves which control admission of steam to the cylinders. The steam is exhausted through a nozzle and up through the smokebox into the stack. This action produces the “chuff chuff” sound heard when the locomotive is moving.
In our demonstration our SD40 was 7.8% of the total weight of the train. It will therefore absorb 7.8% of its own HP just moving itself. The steam engine will do the same thing. But steam engines are usually rated at DRAWBAR HP not cylinder HP.
Using contemporary engineering texts, Shimko found that simple steam engines like Denbigh's typically burned about five pounds (2.27kg) of coal per horsepower per hour.
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.
The water is still nearby, but it's now in a gaseous form called steam. This form of water is also called water vapor, and it's very powerful stuff. This is because steam has a lot of energy. This is because as you continue to add more heat, more water molecules turn to vapor, and then you're not heating them anymore!
Steam engines use hot steam from boiling water to drive a piston (or pistons) back and forth. The movement of the piston was then used to power a machine or turn a wheel. To create the steam, most steam engines heated the water by burning coal.
The most direct pollution problem created by the locomotive was the carbon dioxide emitted into the atmosphere. It gave way to poor air quality and poor living conditions. Additionally, the steam locomotive supported businesses and industries where pollution was an accepted and normal thing.
What steam power enabled was cheaper and more efficient control of labor. Slavery solved that problem just as steam power solved the labor supply problem in England.
If the steam train was never invented, people would have found gold much later. The Gold Rush would have lasted longer because not many people could travel to the west. Also, the gold would have been worth much more if it was found later.
This Amazing Steam Locomotive Cost $5 Million And Took 18 Years To Build. Ian McDonald/A1SLT At one time long ago, steam was the way to power a train from point A to point B. The steam locomotive was a tradition in England, but the last new steam train was released in 1960 as gas and electric took over the railways.
Who invented coal engine?

England had large supplies of coal that were near the surface, which meant that it was cheap to mine, so it quickly replaced wood for heating and cooking and stuff. But, because there was all this incentive to get more coal out of the ground, steam engines were invented to pump water out of the mines.
During the Industrial Revolution, steam engines started to replace water and wind power, and eventually became the dominant source of power in the late 19th century and remaining so into the early decades of the 20th century, when the more efficient steam turbine and the internal combustion engine resulted in the rapid
For portable or mobile use, such as steam locomotives, the two are mounted together. The widely used reciprocating engine typically consisted of a cast-iron cylinder, piston, connecting rod and beam or a crank and flywheel, and miscellaneous linkages. Steam was alternately supplied and exhausted by one or more valves.
Revenues had sunk to a dangerous level just because of struggling economy. But profits had also been declining steadily since 1920. The only way to survive was to reduce costs and improve efficiency.
The locomotive set two world records for steam traction, becoming the first steam locomotive to be officially authenticated at reaching 100 miles per hour (160.9 km/h) on 30 November 1934, and then setting a record for the longest non-stop run by a steam locomotive when it ran 422 miles (679 km) on 8 August 1989 while
Steam power developed slowly over a period of several hundred years, progressing through expensive and fairly limited devices in the early 17th century, to useful pumps for mining in 1700, and then to Watt's improved steam engine designs in the late 18th century.
Steam engines and turbines operate on the Rankine cycle which has a maximum Carnot efficiency of 63% for practical engines, with steam turbine power plants able to achieve efficiency in the mid 40% range. In earliest steam engines the boiler was considered part of the engine.
During the very early days of steam locomotives, water stops were necessary every 7–10 miles (11-16 km) and consumed much travel time. With the introduction of tenders (a special car containing water and fuel), trains could run 100–150 miles (160–240 km) without a refill.
Until about 1910, plenty of entrepreneurs looked at the new electrical drive system and opted for good old-fashioned steam.
Steam power became the energy source for many machines and vehicles, making it cheaper and easier to produce commodities in large amounts. This in turn increased the demand for raw materials used to build more machines that can produce even more commodities.
The steam locomotive changed transportation by allowing us to ship goods and travel faster than ever before. It gave us the ability to create new industries and mold transport into what it has become today. The steam locomotive was an icon of the industrial revolution in many countries throughout the world.
A The color of exhaust you see coming out of a steam locomotive's smoke stack indicates how efficiently it is burning fuel. Darker or blacker smoke is an indication that small fuel particles (coal, wood, fuel oil, etc.) have made it through the firebox unburned and are therefore wasted.
There are currently over 400 former BR steam locomotives preserved in Britain (not including many additional former industrial examples).
The chimney (smokestack or stack in American and Canadian English) is the part of a steam locomotive through which smoke leaves the boiler. Steam locomotive exhaust systems typically vent cylinder exhaust through the chimney to enhance draught through the boiler.
The steam engine was one of the most important technologies of the Industrial Revolution. It was a simple device that used boiling water to create mechanical motion to be utilized in useful work.
How did steam locomotives lower the cost of transporting raw materials and finished goods? They could transport many materials or goods at once. What was the most important role textiles played in the Industrial Revolution? Machines invented to mass-produce textiles led to other inventions.
