Built by Robert Stephenson and Company, Locomotion No.1 was the first steam locomotive to pull a purpose-built passenger carriage. It ran on the opening day of the Stockton and Darlington Railway in 1825. The Stockton and Darlington Railway was the first steam hauled, public passenger railway in the world. This achievement of nineteenth century engineering provides a good starting point for examining the subsequent rapid adoption of railways and the impact of passenger rail travel on Victorian Britain.
