Duncan:
I do not know much about the K-Line but your last question is easy.
CB&Q Rule 221 states:
"A fixed signal must be used at each train order office except
as otherwise indicated by timetable."
That is the first sentence in a rather long rule that covers what
requirements govern the Operator and Train Crews with regard to
train order signals. Does it also say that "All trains must receive
Clearance Form A"? If it does, then by simple logic there is no
reason to have a train order signal.
