I have the April, 1994 ATSF timetable. Under “Radio Communications” the following is listed:
RADIO _______________Tone_Call-In
COMMUNICATION_____CH___DS___SC___MC___CQS__EMER
Holiday to N.R. Jct. _20____2_____3_____4_____5______9
(Apologies for the underlinesl. It is the only way I know to insure
everything will line up.)
I understand CH is the AAR radio channel. I suspect that DS is the
Dispatcher tone number and EMER is the emergency tone number.
I haven’t had much luck puzzling out the abbreviations “SC”, “MC”,
and “CQS”. Can anyone help me complete my understanding of this?
Thanks!
