The year is 1863, and the race to connect the country has begun! Join chief engineer Jack Casement and his sister Sarah Casement, the land surveyor, as we sign with either the Central Pacific leaving Sacramento or the Union Pacific leaving Omaha to help lay track all the way to Promontory Point, Utah near Salt Lake City. Along the way, make peace with Native Americans and watch out ahead for natural disasters, buffalo stampedes, and a band of ornery outlaws out to steal the Golden Spike and sabotage the Transcontinental Railroad.
