Today I added two more engines to my collection and was wanting to do research to find out more about them. Years ago I had a diesel spotters guide but I can not seem to find it. After several years and moves, who knows where it is. Is there an internet site someone can hook me up with that will help? Specifically, I am looking for Rio Grande, GP-40, #'s 3131 & 3141.
Thanks.
Thanks.
