When did James watt create the rocket train?

Answer 1

James Watt didn't invent the rocket train, although that train did use a steam engine that was sort of invented by Watt. James Watt was credited with inventing the steam engine, which was actually invented by Thomas Savory (1700) and Thomas Newcomen (1705). Watt worked at improving Newcomen's model and made a lot of significant improvements in the 1760s and 1770s. George Stephenson is credited, sort of, with inventing the locomotive. He put a steam engine on a rail cart used for extracting coal from a mine in 1814. In 1825, he opened the first railway. His first "train" used a track gauge of 4'8 1/2" - which is still used today by 60 percent of the world's trains. The Rocket was built by Stephenson and his son in 1829. It cruised at a whopping 29 mph.
