A westbound Rapid City, Pierre & Eastern train passes by the power at the Harvest Land Cooperative elevator near Springfield, MN. The Harvest Land engine started life as a Detroit, Toledo & Ironton GP7 way back in 1951 before later being rebuilt at the IC shops in Paducah, Kentucky into a GP10. The RCPE 3429 is a little younger, having been built for the Union Pacific in 1980. Being 40 years old myself, that doesn't sound too old.
