The U.P. Trail

The U. P. Trail narrates the story of William Neale, a young engineer working for the Union Pacific railway. He must contend with Indians, bandits, badlands, and bad weather to get the train to the destination. The railroads are expanding to link the nation, with the celebrated golden spike marking the spot in Utah where the Union Pacific and the Central Pacific would meet.

Published in 1918, The U. P. Trail became a bestseller for Grey, and was made into a film in 1920, starring Roy Stewart and Kathlyn Williams.
