Who invented trains?

George Stephenson was considered the father of railways.

Later, Henry Flagler was the founder of what became the Florida East Coast Railway.
The first train was NOT made by Stephenson (His famous Rocket), Richard Trevithick (assisted by Andrew Vivien) invented a steam locomotive/engine in 1804 although this was not a passenger train. Trevithick's engine was used in and for the mines in South Wales for hauling ore and coal. Stephenson's Rocket WAS the first passenger train running between Stockton (on the river Tees) to Darlington (in County Durham).
