History of Stone rails and Wooden rails

Stone rails

The earliest evidence of a railway found thus far was the 6-kilometre (3.7 mi) Diolkos wagonway, which transported boats across the Corinth isthmus in Greece during the 6th century BC. Trucks pushed by slaves ran in grooves in limestone, which provided the track element, preventing the wagons from leaving the intended route. The Diolkos ran for over 1300 years, until 900 AD.[citation needed] The first horse-drawn wagonways also appeared in ancient Greece, with others to be found on Malta and various parts of the Roman Empire, using cut-stone tracks. An example of stone track still exists on Dartmoor, England, where the Haytor Granite Tramway was built in 1820 using grooved granite blocks.

Wooden rails

Railways began reappearing in Europe after the Dark Ages following the collapse of the Roman Empire. The earliest known record of a railway in Europe from this period is a stained-glass window in the Minster of Freiburg im Breisgau dating from around 1350.[5] By 1550, narrow gauge railways operating with wooden rails were common in mines in Europe.[6] The first railways in Great Britain (also known as wagonways) were constructed in the early 17th century, mainly for transporting coal from mines to canal wharfs where it could be transferred to a boat for onward shipment. The earliest recorded examples are the Wollaton Wagonway in Nottinghamshire and the Bourtreehill - Broomlands Wagonway in Irvine, Ayrshire. Other examples can be found in Broseley in Shropshire, where wooden rails and flanged wheels were utilised, as on a modern railway. However, the rails were prone to wear out under the pressure, and had to be replaced regularly.
