Orchard Combat Training Center Rail Addition

Project Summary

The Orchard Combat Training Center is a 143,000-acre training center located 18 miles south of Boise within the boundaries of the Nelson Snake River Birds of Prey National Conservation Area. The site is used for training by the Idaho National Guard and Army Reserve.

IMCO constructed seven new rail spurs, new rail siding, a marshalling area, and supporting facilities for the loading and unloading of military equipment and supplies at the Orchard Combat Training Center. Crews also installed a water line and complete storm water system, pouring 25,000 cubic yards of concrete, and moving 1.2 million tons of imported aggregate materials.

This project provides the Orchard Combat Training Center personnel with a solution for loading and unloading military equipment and supplies around 60 acres of the site.
