If I see a locomotive and have a camera, it is highly probable that I will photograph it. Here are scans of Kodachrome 25 slides with my HP PhotoSmart scanner. I have no information on when or where they were taken beyond what I find in the pictures themselves.
To the left, Santa Fe Engines probably in August 1941 in Texas and New Mexico
To the left, these engines are from the New York Central.
These engines were probably at Thurston, Ohio, around 1942-4
To the left, engines from the Pennsylvania Railroad.
Probably around Columbus, Ohio, 1942-5
