An HO scale kitbashing article for the UP cars by Gary Binder and Steve
Orth appeared in Vol 15 No 3 (Summer 2001) issue of the UPHS
Streamliner, including an equipment diagram and prototype photos. The
base kit used was the Intermountain R-40-10 with underframe
modifications, Tichy Youngstown doors, Red Caboose rectangular panel
roof, and ASF Ride Control, Symington, or Allied Full Cushion trucks.
This issue of The Streamliner is still available from the UPHS:
