TRAINS arrived today, and on page 65 is a Charles Mahan, Jr. photo of Frisco 186 with train 609 in tow. The shot, which was taken in Tulsa on Sept 19, 1951, shows the 186 still with the doric fret-work as God intended. The two-car train has a fish-bellied 4-door baggage, 15-foot RPO car. The second car is a RPO-chair combination.
