Union Pacific to Increase Maximum Speed Through Gladewater for Efficiency and Safety

Spring, Texas, May 23, 2006 – To improve efficiency and safety, Union Pacific will gradually add 30 mph to its maximum freight train speed, and 39 mph to the maximum passenger train speed through Gladewater, beginning June 5.

Following Federal Railroad Administration (FRA) regulations, the railroad will gradually increase the maximum speed limit from 40 mph to 70 mph for freight trains and to 79 mph for passenger trains that operate on its tracks through Gladewater. The train speeds will increase by five mph each week beginning June 5. By the week of July 10, freight and passenger trains traveling through the area will be able to operate at their new respective speeds.

Union Pacific’s track improvements have made it possible for the FRA to upgrade the track classification from Class 4 to Class 5, allowing for the speed increases.

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.
