Steam locomotive diagrams-where to find? - Classic Trains Magazine

By "diagrams", do you mean drawings a few inches long? Or drawings 9 inches long like in Rwy Age or the Cyclopedias? Or much larger drawings?

If drawings 3-4 inches long are good enough, the book on RI locomotives might have them. I'll check to see if Collias' book has them for MoPac.

If 9-inch are good enough, we can check the Train Shed and other Cycs to see what selection they have, if you say which classes you want.
