Train vs. plane has been a debate for many years. There are definite perks to both modes of travel. Planes can get you to and from your destination much faster, but they do not have the fantastic views and historic qualities of trains.
Traveling by train was the standard for many, many years. The first steam engine was built in 1804, and there were some concerns with the speed of the train, and whether or not people would get sick from riding on them, or be unable to breathe due to the rapid motion of the car. However, by the following year, it had become the fastest method of transportation, and tracks continued to spread across America.
One of the best parts of traveling by train is the amazing scenery that you are going to get to see along the way. America is full of beautiful landscapes, and many of the tracks go through some truly once in a lifetime views. The prices can vary, dependent on where you are going.
Some train tickets are more expensive, but as a whole, they are cheaper, due to the extended travel time. The length of your desired destination will be based on the number of stops, and the regulated speed at which the trains can operate.
