[N&W] Re: J-Class Marker Lights

[nw-mailing-list at nwhs.org]

N&W dispensed with the use of classification signals in single-track CTC and
double-track ABS territory operated under rule 251 of the rule book.  All
classification lights would have been dark.  All freight trains were run as
extras by superintendent's bulletin superseding the timetable schedules -
that let scheduled time freights leave ahead of time if the yard got them
ready.  No green flags or lights were used to denote sections of schedules,
either.
The lead J of the Eisenhower doubleheader would have carried white flags as
an extra on the Punkinvine, though; that was train order single track
territory - no CTC.
