We play with bigger models down here on the Comanche & Indian Gap Railroad
That is a pic of my grandfather on his decapod that he built himself. He built a massive 7.5" gauge, point to point railroad on the ranch starting in 1972 pretty much all by himself. By the early 80s he was hosting meets for live steamers and railroad enthusiasts from around the world. His main goal was to have a complex railroad capable of conducting full operations, unlike a lot of other large scale railroads that are essentially a big circle. The HO guys love to come out for a week in the spring and they are serious about their operations. The C&IG is still going strong and even growing thanks to help from a great railroad community. I got to grow up on this railroad, and while I don't have "the bug" like most of these guys do, I do really enjoy it. The video is obviously a bit dated, but it was a really well done video at the time and I like it. I like how much live steam is in it; it is getting more and more rare even in the model railroad community and that is my favorite part. There are more current videos on youtube if you feel like digging around. I also included a pic of the current track layout. We have added probably another mile or so of main line since that video was taken.
