๐ Why rails?
A train's metal wheels roll very easily on smooth rails, so a locomotive can pull very heavy wagons with less effort than trucks need on roads.
๐ The first railways
Railways began in England about two hundred years ago, with steam locomotives pulling wagons of coal and passengers. Then railways spread across every continent.
๐ก Very fast trains
Japan, France and China have very fast trains that travel at more than 300 kilometers an hour. In Saudi Arabia the Haramain high-speed train runs between Makkah and Madinah.
๐ฏ The Hejaz Railway
More than a hundred years ago the Hejaz Railway was built from Damascus to Madinah to carry pilgrims, and some of its old stations are still standing.
