Are there any scale drawings of the monorail in the book?
None that I can find. There is a full page blueprint type drawing from Bob's Community Transportation Services days showing various sides of a monorail but there aren't any dimensions on the drawing. The drawing title is Basic Model Typical Configurations
There is a lot of good technical information about the monorails and Viewliner in the book.
I forgot one chapter that is train related which is titled "Steam Freaks". The sub title for this chapter is "Longenfelder, Bagley, Kinball - Disneyland locomotive first steam up".
