At some point or maybe over a period of time the track arrangement at Cimarron changed. Originally the roundhouse was by the Depot and it was all stub switches, mostly 3-ways. In the later years the second roundhouse was built by the stock yards and there were still stub switches, In the last years, I suspect when heavier rail was laid for the K-27s the track plan was changed again and point switches were installed. In the last years most RR structures disappeared except for the Depot and the 2-spout tank. Even the look of the trestle on the main changed over time due to rebuilding. JP
