Check out our store for more trains and other vintage collectibles. Really cool piece of railroad history. From the estate of a C.O.O. of BNSF railroad. Has “Union Pacific Railroad” on it but I don’t see any other markings on it. It does look like there was something else near the center of the plate but has since worn off (see picture 4). Its a 6" plate, I think it's a desert or bread and butter plate but I could be wrong. Please see pictures and let me know if you have any questions.
