Bob:

Thanks for the details. I did not know if the red signal light was
activated through the PC switch, a contact on the automatic brake valve,
or some other air brake location. I guess I'll tear up my draft to
Challenger Models complaining about a lack of a PC light on the backhead
of their S4. 8-)

Somewhere in my files is a card instruction Enginemen on the use of the
red signal light. Someday, soon, I'll dig it out and post it verbatim on
this list.
