Book:
Union Pacific Equipment, (2005 reprint) William W. Kratville and Harold E. Ranks. (1969).
Nice book. I recommend it. Great prototype photos and detailed diagrams. I picked it up primarily in anticipation of the GGD Harriman passenger cars. I knew I would have to accept the interpretation, but I wanted to see how close they'll be to actual UP.
GGD based the coaches on the SP 60-C-5. As common standard arch-roof they look very close to the UP Chair cars, the observation not so much. Have to see the actual models for more comparison.
