Development


Using Railways is not a new thought because the idea of  "tracked" roads is at least 2000 years old; quarries in Ancient Greece and the Roman Empire used cut stone tracks to haul loads pulled by animals, as the Greek did for transporting ships overland. Then man started to use wagons, with man or horse power, and track guides made of stone or wood. Historians do not agree upon the exact origins of rail transport; some look upon early conveyances that involved some sort of wheeled device mounted on a system of wood rails as the forerunner to modern rail transport; others tend to consider the real history of rail transport as beginning with the development of the steam engine. With the steam engine came the idea of creating a conveyance that would move by using steam pressure to turn the wheels on the device. In order for this type of railway transport to function, metal tracks were laid down and connected with heavy wood ties on the underside of the track. The ties kept the two rails in proper alignment and helped to make the locomotive more stable when moving along the track system.
