What happened and why it matters

The transcontinental railroad turned a coast-to-coast journey of months by wagon or ship into about a week by train, creating the first national freight market in the US. The Central Pacific built east from Sacramento, largely with Chinese laborers, and the Union Pacific built west from Nebraska, meeting at Promontory Summit after laying about 1,776 miles of track between them. The news went out by telegraph as a single word, done. Western farms, mines, and towns could now ship goods east and receive manufactured goods in return, the base of today's rail intermodal corridors that carry imported containers inland from West Coast ports.
