Hi ALL I am looking to get some guidance from more experienced members on my modelling of Union Pacific locomotives Alco RSC-2 [1280-1289 renumbered as such in 1955] Precisely I would like to know in what period of time this locomotives lost they side slogan SERVES THE ALL WEST/THE WAY OF THE STREAMLINE to gain the new slogan started in 1959 DEPENDABLE TRANSPORTATION ? The only pic I could find shows only one of this locomotive with the latter slogan in 1970 but I believe they received the new slogan earlier that 1970 Can some one help me with a time period even if approximated ? thanks very much for your reply
