Train, one of mankind’s modern means of transportation, is a typical example of mankind’s use of fossil energy for transportation. It refers to a vehicle running on a railway track, usually consisting of multiple carriages.

The most important mechanical means of transportation in human history was called a steam locomotive in the early days and ran on an independent track. Railway trains can be divided into freight trucks and passenger cars according to their loads. There are also passenger trucks that combine both.
