Union Pacific Raises First Quarter and Full Year Earnings Projections

Omaha, Neb., March 14, 2006 – Union Pacific Corporation (NYSE: UNP) today announced that it is raising its expectations for first quarter earnings to a range of $1.00 to $1.10 per diluted share. This compares to the previous expected range of $0.80 to $0.90 per diluted share. Last year, the company reported first quarter earnings of $0.48 per diluted share, which included the $34 million net income impact of the January West Coast storm.

The drivers of the increased projections are stronger than anticipated commodity revenue growth and greater than expected operating margin improvement. First quarter 2006 carload volume is expected to increase 4 percent versus an original outlook of 3 percent growth. Total commodity revenue should grow approximately 17 percent versus original expectations for 15 percent quarterly growth. The revenue upside is driven by strong demand for Intermodal, Industrial Products and Agricultural Products, somewhat offset by lower than anticipated coal volumes. Ongoing mine production issues, especially in Colorado, have been the primary factor in reduced first quarter coal loadings.

First quarter operations benefited from mild winter weather, network management initiatives and capacity improvements, which combined to improve margins.

"We are very pleased by both the robust demand for our rail services and our ability to move record first quarter volumes more efficiently," said Jim Young, president and chief executive officer. "We are leveraging more of our strong revenue growth to the bottom line and our operations have benefited from a mild winter.

"We could still face challenges before we close out March, but we have made operational gains in the quarter. Customers are also seeing greater consistency in our train operations and ongoing efforts to increase network capacity should facilitate service improvements throughout 2006."

The company had originally expected to earn between $4.60 and $4.80 per diluted share in 2006. Current 2006 expectations are now $4.80 to $5.00 per diluted share, reflecting higher first quarter expectations.

"We are optimistic about the ongoing strength of the economy in 2006, but remain mindful of the challenges associated with moving record volume across our system," said Young.
