It was invented in Birmingham England.

Answer 2

The first steam locomotive prototype was built in 1784 by William Murdoch, who was born in Scotland and worked as an engineer and inventor in Birmingham, England. The prototype was the basis for a later design that could carry 4.5 tons of cargo in addition to the driver.

The first locomotive to be able to pull cargo cars on a track was developed in 1804 by Richard Trevithick, a British inventor and mining engineer. It could pull five cargo and passenger cars at a speed of 4 km/h.

In 1820, George Stephenson, English civil and mechanical engineer, overcame the problem of the weight of the engine crushing wooden and iron rails by distributing he weight with a series of wheels and built the first successful railway. It was a line of 8 miles, from Hetton to Sunderland and the first rail that did not use animal power.
Trains, in some fashion or another, have been used since early Greek civilizations. They were common all over and therefore difficult for historians to pinpoint where the very first train was built.
Well, that depends on your definition of train. If you just mean a railway, the history goes back to Corinth, where slaves pushed trucks along tracks in limestone. But if you mean a steam locomotive it would be in England. Richard Trevithick developed several locomotives in the years 1801-1804.
