My interest in things PRR began in 1947 under our Christmas tree when Santa left me a 3/16" scale 3 rail O gauge American flyer # 561 locomotive and 4 car tinplate train set. The AF #561, other than track gauge, was scaled from PRR K5 5698. The train set was apparently a pre-war "leftover", as by that date American Flyer had moved to 2 rail S gauge. After 3 Christmases I wore the K5 out only to discover repair parts were no longer available.
Fast forward 50 years and I arranged for friend and fellow O scaler Frank Miller to build a 2 rail model of 5698. Researching the prototype was fun and interesting as 5698's appearance greatly changed over its service life. PRR documents and photos showed that it didn't get the front end modernization treatment until 1948. To capture the look of my first locomotive I decided to base the model on how 5698 looked in late fall of 1947. With support from Joe Acri, a PRRT&HS member and archive researcher, we obtained prints of several railroad drawings to guide Frank's efforts. Other than the mechanism and tender (from a PSC K4s), the model was scratch built. Beyond prototype research, my contribution was painting, lettering, and installing DCC. Our joint efforts resulted in a first place steam locomotive award at the 2002 PRRT&HS annual convention.
Today I find I'm hosting a growing number of layout visits with people asking how I got started in the hobby and why I model the Pennsy. To partially answer that question I purchased a near mint American Flyer #561 on eBay which is displayed in the stairwell to the train room. Below is a photo of the two locomotives side by side. While I’ve been acused of being a SPF and rivet counter, back in 1947 that 3/16 scale K5 didn't look at all strange on O three rail track.
