[CBQ] Re: Marker LIghts

["poodles53218" <lanceb@walthers.com>]

Here's a trick to help remember this: the lamps on the front of an engine 
indicate the "class" of train and are "classification lamps." Red lamps "mark" 
the rear of a train no matter what kind of equipment carries them and are 
"marker lamps" or "markers." 

On the engines, stick with clear, as they fit the majority of situations ? a 
regularly scheduled train displays no signals day or night ? engines do have 
class lamps, but they're just along for the ride, not illuminated and clear 
jewels or lenses simulate this nicely.

Signals indicating sections and extras are only used when needed:
 
A section is one or more trains operating on the same schedule. The first and 
all following sections, except the last, must show green flags by day and green 
lamps by night. 

An "extra" is any train not listed in the employee timetable. Here, the engine 
must show white flags by day and illuminated white lamps by night.  

If you're looking at displaying these signals for layout operations without 
adding working lamps, the easiest thing is to stick with clear lenses and use 
removable flags.
