God, I miss thoes rotating track switches into and out of the maintenance bays, it was a thing of wonder to watch them in action. I got to see them load and unload trains on very busy days on 2 occasions in my lifetime, it truly was a sight.
Those exact switch tracks were what inspired me as a kid to want to be a roller coaster designer... Before I realized how incredibly difficult that'd be and gave up on my dream to pursue a more stable career choice
