Before the railroad, you needed around six months to travel from the coast of California to New York and after it started with the operation you needed only around one week. This meant more expansion of the industry, trade, businesses, and expansion of populated areas. Unfortunately many Native American tribes were displaced and the US military was called in to fight the tribes.
The trade happens through the trade blocs that were put in place.
Explanation:
Communist regimes that are not economically liberalized still trade with the world through their trading blocs.

Thus the dealing is usually with the government directly.
