???Markers???

I believe C&O used yellow.

NO NO NO ndbprr...you're not talking about markers, you're talking about class lights. These are the light fixtures mounted on the smokebox front of steam engines at about the 10 and 2 oclock positions. You're right about the white and green colors but white signified an extra (not scheduled) train and the green indicated a section of a scheduled train with another section following. Markers were generally at the rear of the train but on an engine running backwards light or at the rear of the train the markers were mounted on the ends of the pilot beam. Pennsy (pre-WWII) had permanently mounted markers on the pilot beams but all other RRs (that I know of) used them on an "as needed" basis. But thanks for the reply.

Pennsy had a numerous markers including white and yellow. i believe white meant second section following.

CP '62 rules say red and green.

I model a wide range of prototypes and I'm in the process of trying to put working markers in all of my cabooses (cabeese?). Most North American RRs normally had a red light to the rear with green to the sides and front. The exceptions that I know of, that used yellow instead of green, are; ATSF, N&W, Pennsy, and (I think) D&RGW and (possibly) Canadian Pacific. Does anybody out there have definitive data on the questionable ones I've mentioned or know of any others that used yellow instead of green?
