George Stephenson is considered to be the inventor of the first steam locomotive engine for railways.
The first railroads were in mines as plateways and then railways in the 1700's. The first railways used stationary engines, people, and horses for power. The steam-engine was adapted for use on iron rails early in the 19th century, and the first steam-powered passenger railway was opened in 1825.
