Hello everyone! This might be an easy question for some, but I've had trouble finding any info. When did B&O switch over to the solid blue with gold/yellow lettering on it's locos? I know it was sometime in the 60's, but not sure exactly when. I work in a public library, & we have several spiral bound books of the B&O in the Ohio area where I live, written by a retired brakeman. 1 pic leads me to believe it was 1961 or prior, but I'm a little doubtful on that. Any help would be appreciated!
