Union Pacific to Increase Maximum Train Speed From Raymondville to San Benito for Efficiency and Safety

Spring, Texas, August 11, 2006 – To improve efficiency and safety, Union Pacific will gradually increase the maximum train speed through the communities of Raymondville, Lyford, Combes, Harlingen, and San Benito to 49 miles per hour, beginning August 28.

Following Federal Railroad Administration regulations, the railroad will gradually increase the maximum speed limit through Raymondville and San Benito from 35 mph to 49 mph, through Lyford from 40 mph to 49 mph, and through Combes and Harlingen from 20 mph to 49 mph. The gradual increase will be five mph per week and four mph on the last week until the new maximum is reached.

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.
