Locomotion No. 1 is a pioneering steam locomotive built in 1825 by engineer George Stephenson. It was designed to pull coal wagons on the newly constructed Stockton and Darlington Railway, the first public railway to use steam locomotives. The locomotive featured a vertical boiler and a single pair of driving wheels, showcasing early railway technology. This locomotive could reach speeds of up to 6 miles per hour and was instrumental in demonstrating the viability of steam-powered rail transport. Its success helped pave the way for the expansion of railways across Britain and eventually the world, revolutionizing transportation.
