Indiana Southwestern (a part of Pioneer Railcorp) GP8 806 was found in Evansville, Indiana, on September 28, 2017, wearing a paint scheme reminiscent of the Nickel Plate Road's diesels. This engine was built an Illinois Central GP7 8969. When Illinois Central Gulf (the railroad's new name after the merger with the Gulf Mobile & Ohio) embarked on a rebuild program for their older GPs, this engine was rebuilt into "GP8" 7969. Eventually, older power, even if rebuilt, becomes a burden and the ICG sold this locomotive to the Iowa Interstate, as IAIS 469. IAIS was doing well and bought new power, so this engine was sold again, this time to IRECO, which numbered it IREX 806. Pioneer Railcorp purchased it, but retained the number (now PREX 806).
