How has the train changed since it was first invented?

Answer 1

Originally, no difference existed between a train and a wagon. A rail was simply a long straight piece of wood. In some places roads were made of planks. They had rails alongside of them to hold the wheels on the road. Thus, they would be a plank road bordered by rails. Such a road was more expensive than one made from dirt but it was much faster for moving ore from a mine.

Then someone put flanges on the wheels so they could ride on the wooden rails. They could also ride on the ground. They were still horse drawn wagons.

Then the T rail was invented. It had a base. It was made of iron. A horse could pull a wagon faster on it than it could pull a wagon on a wooden rail.

Then someone created a steam engine to pull the wagons.

Then as trains got faster, someone added stagecoaches to trains and carried passengers. Then special railroad cars were invented to carry passengers.

The special cars became heated.

Steam engines became faster.

Brakes were added.

Then they were replaced by diesel and electric engines.
