Union Pacific to Increase Maximum Train Speed by Six to 11 MPH in Certain Areas from Humble to Diboll

Omaha, Neb., April 2, 2007 – To improve efficiency and safety, Union Pacific will gradually increase the maximum train speed of freight trains by six to 11 miles per hour in certain areas from Humble to Diboll, excluding Livingston, effective today.

Following Federal Railroad Administration regulations, the railroad will gradually increase the maximum speed limit for freight trains by five mph per week until the new limits are reached. The speed limits in some areas in the Diboll to Humble rail corridor will increase from 40 mph to 50 mph, others from 49 mph to 55 mph, and others from 49 mph to 60 mph.

This measure is expected to improve public traffic flow and grade crossing safety by increasing train traffic fluidity through the area. Statistics show that more highway-rail grade crossing collisions occur at slower train speeds. At the same time, slower train speeds can cause traffic delays as trains occupy crossings longer.
