All-Time Record Carloadings Highlight Union Pacific's Improved Service

Network Management Initiatives and Capacity Investments Drive Performance

Omaha, Neb., June 16, 2006 – For the first time ever outside of peak season, Union Pacific on Thursday set a new all-time record for carloadings in a seven-day period by hauling 200,700 railcars for customers across North America’s largest railroad. Prior to this week, the seven-day carloading record was 198,416 set during peak shipping season on November 23, 2005.

"Reaching this record level in June, before the fall peak shipping season, is an indication of the improving efficiency of our railroad and the strength of demand for our services," said Jim Young, President and Chief Executive Officer. "Especially encouraging is the fact that we handled this record volume with improved velocity and reduced terminal dwell compared to last November. This is the result of our network management initiatives and investment in capacity. While I’m pleased that we are providing more efficient service to our customers, we remain focused on driving further improvements."

Current Business Group Service and Volume Highlights Include:

  • Overall, second quarter volume is up 5 percent through the first ten days of June.
  • Agricultural Products volume is up 3 percent. Ethanol growth, Mexico imports, feed and corn shipments are all running above last year’s levels. Union Pacific is handling a 57 percent increase in ethanol shipments, fueled by growing demand and continued development of ethanol unit trains, which provide faster transit times versus normal carload movement.
  • Auto volumes are continuing their growth trend from the first quarter, up 5 percent. Improved multi-level load-to-load cycle times and improved performance on auto parts resulted in a record May and the fifth-highest volume month ever.
  • Chemical volume trends have improved from a slow start in April and are flat quarter-to-date. Weaker fertilizer volumes are offsetting strength in petroleum products, plastics and phosphate rock. Dwell time, a critical service measure for the chemical business, has improved.
  • Energy volumes have turned around significantly from the first quarter, up about 8 percent, quarter-to-date. May was a record month for coal shipped from the Southern Powder River Basin, as well as a record month for loadings originating on the North Fork Branch in Colorado. That success made May the second-highest month ever for Union Pacific coal loadings, topped only by March 2005.
  • Industrial Products volumes are tracking below the strong trend seen in the first quarter. In particular, softer lumber and paper volumes have offset growth in steel and rock shipments. May was the best month ever for rock carloadings – 34,442 – with the southern Texas rock network leading the way with 28,322 carloads. This tops the previous southern rock record set in August 2002 and helping to drive the largest May rock volume since 1996.
  • Intermodal volumes remain strong, up 7 percent in the quarter, and new volume records have been set every month thus far in 2006. Service has improved for Blue Streak – Union Pacific's truck-like priority service for intermodal containers and trailers – and customers are voting with their business. Volume for Blue Streak has doubled year-over-year.
