When and why were steam trains first invented?

Although James Watt is most strongly associated with the invention of the steam engine as an engine, interestingly, the first engine was patented by Thomas Savery in 1698. James Watt, a Scotsman, improved on the design of the steam engine in the second half of the 18th century, so that it could power the industrial revolution and eventually locomotive travel.The man who first put steam engines on rails was Richard Trevithick, who built a 'Pennydarren tram road engine' for a line in South Wales, UK, to replace horses that had been pulling the wagons.In 1804, Trevithick's engine succeeded in pulling 10 tons of iron and 70 men to a distance of nearly 10 miles from Pennydarren near the industrial town of Merthyr Tydfil, at a speed of 5 miles per hour. Recognition eluded Trevithick in his lifetime, and his engines were seen as just a novelty. However, others developed the idea, and by 1845, Britain was covered by 2440 miles of railways, carrying 30 million passengersThe prime point of the steam locomotive was to carry natural resources such as iron and coal... and also passengers.Richard Trevithick (13 April 1771 - 22 April 1833) a British inventor, built the first full-scale working railway Steam Locomotive. On 21 February 1804 the world's first railway journey took place as Trevithick's unnamed steam locomotive hauled a train along the tramway of the Pennydarren ironworks, near Merthyr Tydvil in Wales, Great Britain.George Stephenson (9 June 1781 - 12 August 1848) a British civil engineer and mechanical engineer who built the first public railway line in the world to use steam locomotives and is known as the "Father of Railways".So, Trevithick invented the first train, Stephenson the first public railway line and the original Steam locomotive was invented and patented by James Watt in 1784, following many years of his work in improving steam engines in general.**Early prototypes of Locomotive were built such as Scottish Inventor William Murdoch 1784.


Why is heat trasnfer coefficient of saturated steam is higher than superheated steam?

when steam is at its saturation point for a given pressure, any heat removed will cause liquid water to form. So when saturated steam is used to heat something else, the heated object/substance receives the condensation heat of the steam. The latent heat of condensation/evaporation is 970 But/lb @ 0 psig. On the other, superheated steam only gives up about 10 BTU/lb if it is cooled 20 degrees F. That means that much more steam would be used to transfer the equivalent amount of heat. The liquid water interface also improves the heat transfer.


How much did steam locomotives cost?

During the Civil War in the United States a standard 4-4-0 steam locomotive would have cost between $10-12,000 . Of course this is when a soldier in the Union army made less than $15 an month.
