Dear Mr. Hemphill, Thank you very much for clearing that up for me. However, I still have some questions. Looking at a signal aspect chart in the Altamont Press Timetable (California-15th edition), I noticed that UP (which I am pretty sure operates under GCOR) has an aspect (Diverging Clear Limited) which would dictate speed through a turnout: Diverging Clear Limited is defined as, "Proceed on diverging route. Speed through turnout must not exceed 40 MPH." The aspect is red over flashing green or red over flashing green over red. Am I mistaken in believing this to be speed signaling? Secondly, the chart mentions a "Plate C." It is defined as "Plate C: Passenger Trains; when next signal displays an aspect more favorable than Diverging Approach or Approach, the requirement to proceed prepared to stop at second signal no longer applies." At the same time, however, I often see "Exceeds plate C" stenciled on freight cars. Are these two related, or just coincidence? Sincerely, confusedly, and gratefully, Daniel Parks
