The Eastern Idaho Railroad (reporting mark EIRR) commenced on November 21, 1993, as a collection of two disconnected clusters of former Union Pacific (UP) branches. A subsidiary of Watco, EIRR operates two segments that move more than 35,000 carloads per year to the Union Pacific, with interchanges at Idaho Falls on the Northern Segment, and Minidoka on the Southern segment. The annual income is reported as being under 25 million dollars. Potatoes are a major commodity carried, using a unique loading technology to minimize damage during transit.
