Signal Technicians are dispatched from the Sylva office or from the Henderson County maintenance yard. They may respond from wherever in the Division they are working. Very often a signal they are called to is working fine when they get there. It is very helpful to report what the signal appears to be doing wrong, and leave a follow-up phone number where the technician can call to ask what problem was observed. Police, Sheriff, and the State Highway Patrol will also relay "trouble calls" to our technicians.
