Stumbled across the first page of this thread and it looks like @furie had shared a video of this!I've always been fascinated by the Triple Racing Coaster, which operated at the Texas State Fair from 1936 to 1946. It just feels like an unfathomable concept for today's coasters, let alone back in the 30s before CAD and other digital design. Texas State Fair as a whole has a rather chronicled history of hosting permanent roller coaster installations through the decades, back as far as 1887!
On Triple Racing Coaster, saw this great high-res shot on Facebook. You can pick out some of the layout; just a fascination to see!
