FREMONT, Neb. (AP) — The chairman of Union Pacific says the railroad has begun a multi-year effort to double-track the route between Fremont, Neb., and Missouri Valley, Iowa, in order to move trains through the area more quickly. Union Pacific chairman Jim Young outlined the $300 million to $400 million project. Young noted there is a lot of single track in that stretch as well as two bridges, which cross the Elkhorn and Missouri rivers. Young says the railroad wants to reduce bottlenecks and prevent trains from waiting in the communities. Young, who spoke with Fremont business leaders on Thursday aboard a train car, says Union Pacific plans to spend $3.3 billion on capital projects throughout its system in the next year and hire 1,300 new employees.
