The Surrey Iron Railway was one of the first railways in the world, planned in 1801 and opened in 1803. Used to transport goods, the wagons ran on cast iron rails and were pulled by horses. Uniquely it was open to the public, making it the first public railway in the world.
It ran successfully for over forty years, but the advent of steam engines spelled the end for the railway. The horses were unable to compete with the speed of steam, and with iron rails unable to take the weight of the steam engines an upgrade was not possible. It closed in 1846.
