O Scale Model Railroading: Crooked Mountain Lines Case Study

A Case Study on Bob Hegge’s Crooked Mountain Lines traction layout is ready for publication in the up coming November/December 2026 issue of The O Scale Resource Online Magazine. I visited Bob Hegge with my Grandfather back in the 1970s when he had an open house for the National Model Railroad Association National Convention in St. Louis. My grandfather was an avid traction modeler in O Scale and knew a thing or 2 from having employment with the Chicago Surface Lines and later retired from the Chicago Transit Authority. There are basically 2 objectives, (1) What a modeler can do when space is limited for an O Scale build, (2) I wanted to become more knowledgeable myself about his techniques not only as a master modeler in the media he choose but also because he was a photo-journalist. If you think about the photography technology back then compared to what we have today, it becomes necessary to understand how he set the scene, lighting and of course dark room work which most people know nothing about these days. Consequently, my approach was similar and very much the same as how art critics interpret beautiful great works of art. I hope that my explanations make good sense. I did this without actually saying so because I know most people are not versed in the terminology that art critics use or how they think or write about it. In order to accomplish this, I collected and compiled photos going way back from a number of sources. Naturally, a rather large bevy of them were black and white. Step 1 was to scan these in a very high resolution on my scanner to study them and try to order them based on the track plan, article explanations and companion photos. High resolution scans on a good graphics adapter and monitor, things pop out at you that you may have never casually noticed before, particularly if the photo source was from an old magazine. Without having the original negatives, that is about the best you can do. Next, I spent a great deal of time asking the various AI tools to describe what they saw in the hi-res images without adding anything in the process. Following that, on some photos, I asked AI to enhance the entire photo or a cropped version, especially photos that were somewhat not the best quality. This gave me a better understanding of the layout by comparing my high-res scans and the outputs from the AI tools. Finally, even more time was spend using AI to assist in colorizing the photos. This turned out to be fairly technical and experimental at the same time. So the development of the case study from the perspective of the viewing public via methods common with artistic interpretation diverged from that of just being a pedagogical model railroad article. I think I have achieved my original goal even though it took me a very long time to bring it all together. It is also very easy using some of the photos like the panorama shots to put the layout in the North Western mountain range as a background. I hope you will enjoy this series of articles when they are published. Visit Us At: https://AllNationLine.com
