I live on the Tennessee Pass line and the Union Pacific is allegedly in talks with the Rio Grande Pacific about the purchase of the line. I am not sure if the RGP would use the same name if they acquire this line. I cannot locate any pictures of any RGP locomotives but I am sure someone out there has some that they can share.
OK I had someone sent me a private message that explains why there are no photos of RGP locomotives. It is because there are none. I guess RGP is made up of 4 short lines. Idaho Northern & Pacific. Nebraska Central. New Orleans & Gulf Coast. Wichita, Tillman & Jackson.
