European immagrants mostly the Chinese went to work on the railroads. It was a hard and dangerous job as some usually died trying to mine and for all their effort they got little pay.

When the railroad opened up ways to get to the west and free land was promised, many of these people left large cities with whole communities of on nationality. The Russians had come to America to produce red wheat, a hearty wheat that could with stand the harsh winters on the plains. Other nationalities did the same. Once the railroad was in, there was a way for immigrants to move in, grow crops and have a way to transport them.
