Looking for information on the make and model of the two lighted
"mars light" that was applied to the roof of CP pass. units. Usually
placed in front of the first set of ice breakers, behind DB fan.
What units had this light applied?
What is the true story behind their application? I have hear of three
different reasons for their use.
Most pictures that I have referred to, show them applied to units
working the Canadian.
Thanks
