Middletown, NY track schematics

Help! Help! Have put off working on my HO layout for a number of years. Having just retired, I find I now have the time. My family lived in Middletown and area for years, (cut my teeth on a Erie caboose) and always loved the area. Can't find a copy of Bill Sheppard's Schematic Track Diagrams of the Erie Lackawanna Railway and would love to model the Erie/E-L from Goshen to Otisville. I remember how much of it goes (outside of Middletown), but would like some help on the track layout esp. the Middletown yard. Been all over the net and several train shows and can't find a copy! No pictures either! Seems once Conrail gave up on this area, everybody else did too! Any help would be appreciated!
