    Those are classification lights. They can be white, green or red depending on what the train is and where the locomotive is in the consist.

    To be absolutely sure, it would be best to check UP's policy on classification lights to get it right.

    Though I can't say for sure on this particular case, most loco class lights have "clear" fresnel lenses with selectable red, clear(none) or green filters between the glass and the bulb, so color is unnecessary, unless you are going to light 'em up. Most new locos come without class lights, and rebuilds often have the openings patched over. Bob C.

    Classification lights. Displayed only on the lead unit. (Steam or diesel.) As almost all real timetable and train order operation is no longer in use, you'll not see these on newer power and often removed, plated over on older units.

    Union Pacific RR- Not lit would usually have been scheduled train. (See Note.) White an extra train. Green a section or section following. Red was not used. Note- Use of class lights could have been altered by a train order or by their failure to operate properly.

    If you can get a copy of the CCOR (Consolidated Code of Operating Rules), predecessor to the GCOR, it's explained therein.

    The PC and Conrail usually left them as red at all times. I used red jewels (MV Lenses) in my PC and Conrail models per Jim Six articles on modeling SD40 and SD 45's.

    As the engine pictured is Union Pacific, my response is relevant to that railroad. And to all others using that same CCOR. (BN, GN, NP, MILW, Soo, etc.) There were different groups of operating codes across North America.

    Red lenses might not have been as classification lights. Instead, that could have been found under rules for marker lights.
