Seeking to recover from a round of delays, Union Pacific will start next week shifting a portion of cargo it carries for the United Parcel Service onto trucks, Bloomberg News reports.

Union Pacific spokesman Norman Black says the company will pay truckers to carry United Parcel packages between Los Angeles and Chicago and between Dallas and Memphis for four weeks.

Union Pacific won United Parcel's business in 2003, offering to deliver freight within 60 hours on a coast-to-coast train once a week in each direction, in conjunction with the CSX Corp.

The railroad is seeking to recover from a round of delays that began last year, costing as much as $50 million.
