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.

Toward the end of their service lives the two K5's served primarily on runs between Harrisburg and Baltimore.  Since my railroad models elements of the Middle and Pittsburgh division I've taken modelers license to use the K5 primarily at the head end of a "special" comprised of heavyweight Pullman's perhaps chartered for a convention run. When I tack on President Truman's Ferdinand Magellan on the tail end it becomes a campaign train.

Mark - that's the 3/16" scale O gauge American Flyer 3 rail # 529 K5 on the left.  Needless to say after taking the photo I quickly I took it off the rails to prevent a short.

 

When AF resumed production after WWII they redesigned their steam locomotive mechanisms for 2 rail S gauge, using virtually the same boiler and tender castings.  I retrospect it's amazing they were able to squeeze an O gauge mech in an S gauged size boiler.

Gasp! What a beautiful railroad! Magnificent work.

Sister K5 #5399 turned in some remarkable horsepower measures: 3862 DBHP and 4267 IHP, at 75 mph. She had a Franklin Rotary Cam System and a modified front end arrangement to more efficiently distribute steam, done by Lima. I have mentioned these figures in conversations with other steam enthusiasts, and was pummeled with "No way a Pacific churned out these measures!"       Care to comment, Ed?

Maybe that's why they run so well. That could also explain the size of the motors in the AF engines; they're huge,and will pull as many cars as one might have on hand.

In any case,I'll add my name to the (growing) list of admirers of your fabulous layout,and yes,I too would love to see a video!

Greg -  Though the track work is complete and fully operational, I've held off doing a video or  photo layout tour until the scenery is further along. You are seeing one of four longitudinal aisles.  The hillside behind the passenger trains is only partially wooded and it won't be until next fall that I can harvest enough dried golden rod to make the 100's of trees I need to finish the scene.  The Horseshoe Curve aisle backdrop is in but unpainted, and its terrain is only partially covered with hard shell.  With all the beautiful finished scenery I see on the forum and in the magazines, I'm reluctant to showcase 2 rail O scale with partially finished scenery.

Guys  - thanks for the kind words.  Influenced by John Armstrong (a Friday night railroading regular), the area around the watering bridge is what John called a "Scenic Curve". It's 12' long, super elevated, and laid on a 1082" radius. I couldn't lay it out  with the usual trammel beam method as the center of radius would be accross the street! To lay it uniformly I used fixed interval offsets from a know reference line taken from the 3rdPlanit CAD drawing of the railroad. 

 

 In retrospect I should have left the curve flat and installed track pans - now that would shout Pennsy Middle Division.
