US-based railroad operator Union Pacific is planning to invest $200m to improve the rail infrastructure in the states of California, Illinois and Idaho this year.
The company will spend $137m in California, with nearly $117m to be used to maintain railroad track, $9m to enhance signal systems and $11m to maintain or replace bridges.
In Idaho, Union Pacific will invest $43m in Idaho for rail track and bridges maintenance, and improvement of signal systems.
The train operator is improving the rail line between Chester and Illinois/Missouri border with an expenditure of $20m.
Illinois will see an investment of $119m for the improvement of infrastructure, covering nearly $105m to maintain railroad track, $5m to enhance signal systems and $9m to maintain or replace bridges in the state.
Funded entirely by Union Pacific without taxpayer dollars, the project is scheduled to be completed mid-October.
With the investment, the company will replace 71,800 railroad ties, install 30,000 tons of rock ballast and replace nearly 15 miles of rail, while crews will repair the surfaces at 43 road crossings.
The project is one of nearly 1,500 the company will complete across its 32,000-mile network this year to help improve train operating efficiency, reduce motorist waiting times at crossings and improve safety.
Union Pacific public affairs, northern region vice-president Donna Kush said: "Union Pacific helps businesses connect with consumers, suppliers and markets across the nation and around the world.
"In addition to helping move our customers’ goods safely and efficiently, our investments support communities by reducing traffic congestion, facilitating industrial development and promoting economic expansion."
The company plans to invest $4.2bn across its network this year, following investments totalling more than $31bn from between 2005 and 2014.
