How many steam locomotives are left?
There are only eight of the 80-year-old steam locomotives left. Big Boy No. 4014 is the only one that hasn’t been turned into scrap metal or a museum display piece. That makes each stop the locomotive makes along its 4,000-mile journey across 10 states a must-see for model train hobbyists and historians.
When was the last steam locomotive used?
The last steam locomotive was used in the US in 1961 by the Grand Trunk Railroad. After 1961, the US had fully moved away from steam, except in special excursion services.
Why is the steam engine bad?
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.
Are steam locomotives still being built?
There is only one place left on earth where steam locomotives are still widely in use: the Chinese industrial hinterland. Rail enthusiasts are now regularly traveling there to witness the last gasps of the engine that created the modern world. Some among them worry it may already be too late.
Does China still use steam locomotives?
The last steam locomotives were finally withdrawn from China Rail in 2003.After that, some continued to operate heavy freight trains on local railways for a short while, but most were deployed for use on the country’s industrial railways, mainly at coal mines and steel works.
Where is the big boy 4014 now?
The locomotive was retired in December 1961, having traveled 1,031,205 miles in its 20 years in service.

Are steam locomotives more powerful than diesel?
Firstly the diesel engine has an impressively high thermal efficiency – with modern diesel engines achieving 45% efficiency compared to a steam engines 10% giving them to achieve greater distances between refuelling stops.
Could steam trains make a comeback?
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.
Why do steam excursions have diesels on the back?
In the interim, until all steam locomotives were modified to work an air-braked train, they were required to be fitted with a through air pipe so a diesel or electric locomotive could be attached in order to provide assistance in the event of failure of the steam locomotive.
Do steam locomotives pollute?
Do steam engines pollute? 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. Early steam engine railway locomotives used wood or coal to fire the steam boiler.
