Trains have been in existence since the 6th century BC in Ancient Greece. Diolkos tracks, or a paved roadway, was used as a transport system until wooden tracks came in around 1500 AD. In the late 1700s, metal tracks became the norm as railway designs changed over time. Mining carts were the first to be used, followed by steam engines, then electric and diesel engines led to the high-speed trains we have today.

Train travel offers a freedom that rarely comes with other forms of transportation. You can move about, enjoy the views from the observation car, get something to eat in the dining car, chat with fellow travelers, and stretch your legs. And there are few better trains for enjoying that experience—along with beautiful views and thoughtful amenities—than these stunning routes around the world.
