Total fabrication?

Is there any factual basis for the following claim, or is this a total fabrication?

"While working for the railroad, [the Chinese] were ... treated poorly ... forced to buy their supplies from the railroad company store at double the prices of privately owned general merchandise stores."

From the article, "Travelin' in Time: Early Chinese pioneers faced hardships in the gold fields." Record-Searchlight, redding.com 9-2-2010
