Union Pacific Lifts Southern Powder River Basin Joint Line Embargo

Omaha, Neb., March 27, 2007 – Union Pacific today announced the end of its embargo on new service from all stations on the Joint Line serving the Southern Powder River Basin (SPRB) of Wyoming.  The embargo, in place since July 18, 2005, officially ended today.

"Western coal from Colorado and Wyoming supports critical energy needs throughout the entire United States," said Doug Glass, vice president – Energy, Union Pacific Railroad. "The embargo was originally put in place during the summer of 2005 when an aggressive track work program was under way to restore full capacity to the Joint Line.  The embargo allowed us to protect service to our existing customers without being forced to transport coal to new customers."

Investments in track infrastructure, combined with incremental operational improvements and less disruptive maintenance schedules helped expand rail capacity on the Southern Powder River Basin Joint Line. Union Pacific has the ability to move coal that its customers demand, although episodic mine production problems may affect deliveries.
