Carlsbad, NMMosaic Potash

This project consisted of a total reconstruction of the entire rail yard. The existing track infrastructure had been in service since the 1940s and much of the original rail was still in the facility. The harsh environment and age of the facility resulted in frequent track failures which were periodically remedied.

This project required that the facility have rail service at all times so proper phasing of rehabilitation was vital. As soon as each track was reconstructed, work began on the next. American Track came across several fatal flaws in the original design (original design by others) and had to perform a comprehensive redesign.
