I found this site today and haven't had much time to explore it but I did find a nice image of Lindenwood in 1971 that shows the roundhouse and turn table. http://www.historicaerials.com/ Patrick
The site is suffers from watermarks every where and print color that is very hard to see. There are better sites elsewhere Tomd6
They did have Lindenwood from 1958 with the 4500s sitting there. Wish I could find some good sharp aerial shots of there from the '30s or '40s. Newburg also!
