The sorting yard at this facility could be a very busy place. Wagons would come down the incline singly to be sorted into short trains to be hauled off into the store. The working incline and opening and closing blast doors would make this an interesting model to watch. The plan below shows how I'd envision the 2 running lines joining up backstage at the Lazy Susan fiddle yard. Interchangeable casettes on here would make for a rapid changing of trains.
