CSX Raised Letter Nathan K5LAR24

Copy the "K5LA_HornControl" proxyxml file, and rename to any locomotive horn sound proxyxml. (ex: "Dash8 Horn"). If your locomotive is Searchlight Simulations compatible, open the locomotive horn sound .bin file with TS_tools or anything else and rename (ex: MLWAudio/GE-FDL16/FDL16/Horn-Bell/K5L_HornControl) and change it to SearchlightSimulations/NathanAirchimeK-series/K5LA_CSX#5311/K5LA_HornControl.
