Ag Valley Co-op 2002, one of two diesels assigned to the grain elevator in Edison ME, was built by General Motors Electro-Motive Division in December 1973 as Missouri Pacific 819, later renumbered to MP 3118. After the Union Pacific acquired the MoPac, this diesel became UP 4118. UP later relegated it to B-unit status, and renumbered it UP B4118 as a result. UP renumbered it once again to UP 8929 before retiring it and selling it to Ag Valley Co-op, becoming AGVX 2002.
