It's in the History - The Railroads Traditional Cache

Many of you know how the country was founded and how it became to what we are today.  But did you know how the country was united?

With the invention of the steam engine, they created early versions of a steam locomotive. At first they only would travel within the boundires east the the Appalachia mountians. Around the mid 1800's they had managed to travel through the mountains using a variety of tunnels and bridges. This now enabled easy expansion to the western part of the country.

The following is a timeline of it's history: (From wikkipedia - See link)
