Crews will complete this track improvement project using Union Pacific's modern track renewal train, the TRT 909. The TRT 909 installs rail and concrete ties in one pass, and can install up to 5,000 ties in a 12-hour day. About 30 cars - each carrying 210 concrete ties - are part of the TRT. Three sets of gantry cranes move the concrete ties forward for the TRT to drop into place and the machine then threads the new rail onto the ties. The old wooden ties are picked up and the discarded rail threaded out as the machine works its way down the track. A conveyor moves the removed ties into position for the gantry cranes to load them onto the cars for movement to a facility for sorting. The TRT 909 can install concrete, composite and wooden ties.
In 2008, Union Pacific's engineering renewal program invested more than $254 million in track work and facility improvements in Nebraska to ensure safe, reliable transportation.
