OMAHA, Neb. (AP) — Union Pacific plans to invest $22 million in upgrades to its western Nebraska rail lines this year.

The improvements to the rail lines between O’Fallons, Neb., just west of North Platte, and the Wyoming border are part of UP’s overall $3.6 billion capital spending plan.

About 150 miles of track will be upgraded by mid-October.

The railroad says the project includes renewing the surface at 93 rail crossings, replacing 93,400 ties and spreading 44,000 tons of rock ballast.

Union Pacific also plans to install 16 miles of new rail on the line that connects to Wyoming’s coal country.
