Question

Who was invented rail engine?

Answer 1

Quote from the source website:

"The first self-propelling steam engine or steam locomotive made its outing on 13 February 1804 at the Pen-y-Darren ironworks. The machine was designed by Richard Trevithick."

The article has all the technical details as well as photographs of the engine.

However, later in the same article it also says:

"George Stephenson, who lived near this colliery designed his first locomotive, Blucher, in 1814, again, for a colliery.

The first public railway was the Stockton and Darlington Railway, whose first run took place on Tuesday, September 27, 1825 with Stephenson-designed locos, the first of which was called Locomotion."
