George Stephenson's Rocket
{"Image DocumentName": "George Stephenson\u2019s Rocket", "Image ImageDescription": "Just a few years later, George Stephenson designed and built the Rocket, the first steam locomotive practical for pulling rolling stock (train cars). The Rocket was a critical player in the advent of the Liverpool & Manchester Railway. The directors of the Liverpool & Manchester company were unsure whether to use locomotives or stationary engines on their line. To help decide, they held a competition in 1829 in which the winner would receive \u00a3500. Each locomotive had to haul a load three times its own weight at a speed of at least ten miles per hour. The locomotives had to run 20 times up and down a track, a distance equivalent to a trip between Liverpool and Manchester. The Rocket won the race, reaching speeds of up to 24 miles per hour.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
