OMAHA, Neb. -- Union Pacific set another company record last month by hauling 18.7 million tons of coal out of northeast Wyoming's Powder River Basin.

The Omaha, Neb., based railroad says it brought 1,190 full coal trains out of Wyoming in August. The railroad's previous best came in July when it moved 1,174 coal trains out of Wyoming.

Through the first eight months of 2008, Union Pacific moved 476 more coal trains out of Wyoming than it did in 2007. That represents a 6 percent increase.

UP vice president Doug Glass says the coal shipping records demonstrate that investment in the lines coming out the Powder River Basin is paying off with higher capacity. Union Pacific and Burlington Northern Santa Fe Corp. share ownership of that line.
