To our Customers:

Union Pacific is making preparations for the arrival of Tropical Storm Gustav.  
The storm, with winds now up to 70 mph, is expected to continue to build to 
hurricane strength by as early as today.  Gustav is expected to reach the Gulf 
of Mexico by Saturday or Sunday - possibly building to a Category 3 hurricane - 
with anticipated landfall somewhere along the Gulf Coast by Tuesday morning.

Rail traffic normally interchanged with the NS and CSX at New Orleans is now 
being directed to the Memphis and St. Louis gateways, in anticipation that 
officials will order the closing of the flood gates in New Orleans, blocking 
rail traffic into and out of the city.  All interchange traffic with the NS 
will be directed to the Memphis gateway, along with CSX manifest traffic.  
Intermodal traffic interchanged with CSX will move over the St. Louis gateway.

Operations personnel are currently moving equipment out of low-lying areas and 
resources are being staged in strategic locations to expedite any necessary 
repairs following the storm's landfall.

In the coming days, as the path of the storm is more defined and landfall 
location is determined, rail operations in the affected area will be 
suspended.  Crews in the area will work to tie down equipment in UP yards and 
work with customers to secure equipment at their own facilities.

We will continue to provide updates on our web site as information becomes 
available.
