Are diesels better than steam engines?
Are diesels better than steam engines? Diesels replaced steam locomotives because that's what they did - they are more efficient because they cost less money to run. This article, written by US locomotive engineer Al Krug in a series of newsgroup posts, tries to explain the power questions that show how diesels are more efficient than steam locomotives.
Do steam locomotives pollute more than diesel?
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.
Are steam trains stronger than diesels?
ton for ton a steam locomotive can and does pull more tons at higher speeds than a diesel locomotive can. The H.P. of a diesel is less effective at faster speeds because more electricity is needed to keep the traction motors spinning at the higher speeds.
Why did diesel replace steam locomotives?
The diesel engine drives an alternator, which produces electricity to run electric motors mounted on the locomotive's axles. The internal combustion engine was a dramatic improvement in efficiency over the steam locomotive, making substantial savings possible in maintenance and the elimination of widespread facilities.
What are 2 disadvantages of the steam engine?
- A steam engine is huge and heavy. ...
- Steam engine has low efficiency.
- Steam engine does not start at once.
- Before a steam engine can start, one has to build a coal fire to get steam which takes a long time.
Which train engine is more powerful?
All hail Mother Russia: with 17,838 horsepower, the Novocherkassk 4E5K locomotive is the most powerful in the world.
Which is better diesel or electric locomotive?
Power plant capacity is far greater than any individual locomotive uses, so electric locomotives can have a higher power output than diesel locomotives and they can produce even higher short-term surge power for fast acceleration.
Why are steam engines no longer used?
Steam locomotives are no longer used to transport passengers or products because electric and diesel locomotives are faster, more efficient, and easier to maintain. The locomotives that are still running are a piece of history dating back to the 1800's that really put into perspective just how far we've come!
