On the Wiki Collaboration Page for Florida there is a link for Florida Railroads. In it you will find a completed list of FEC RR Defect Detectors complete with call sign and coordinates to there exact location. Also under CSX I have completed all of the Subdivisions for the Jacksonville Division. There a more condensed version of the CSX Timetable's. They provide info such as major locations (by milepost) along each line, junctions with other CSX lines & railroads and the special attention was put on Defect Detectors providing there exact location by coordinates as well as the frequency they transmit on and there FCC call sign. The only problem is some subdivisions are listed under "Florida Division" and most are under "Jacksonville Division". But there all there. I hope any Florida Railfans like myself will find this useful!!!!
