By the time I had begun to notice things, the Frisco interlocking tower was a thing of the past, and it wasn’t until I began perusing the Northern Division B&B records that I discovered KY Tower in Rosedale, KS. Frisco’s Rosedale or KY (short for Katy) Tower stood at MP C-3.2, and it governed the movement of MKT trains as they entered the Frisco double tracked mainline at that location. It’s location was off the beaten path, and exploring the 19th Yard was always more interesting, so I never attempted to locate its exact location. I did produce an imagineered drawing of the structure based on the B&B record. I hoped to find a photograph or two, and then build a HO scale model. Using Google Earth, I believe that I have located the foundation of the interlocker. The dimensions in the satellite photos match the dimensions of the structure. The foundation is located in the dotted-blue rectangle. The location is very close to MP C-3.2, and the location between the MKT mainline and the Frisco mainline seems to be a reasonable spot to place an interlocker. The interlocker was closed when the Frisco replaced the ABS system with CTC which was about 1954-55. A local CTC machine was placed in the office building at Rosedale. It controlled traffic between Cross-over B and 29th Street. The first-trick operator was John Hatch, and he indulged my brother and me on many occasions. Do any of you KC guys have photos or plats that depict KY tower?
