Class/marker lights of GMD-1

[faraway]

The new Rapido GMD-1 has four white lights at the corners.

I understand that lights as white class lights to be used to indicate an extra train. There is little use for an extra whith my little industry switching layout.

But I think I could make use of red marker lights at the back when running light or shoving a cut of cars.

Question:

Had the prototype CN GMD-1 fixed white bulbs and glasses to be used as class lights only (no green?) or could and can the prototype show red marker lights?

ps. Rapido writes about the model lights but does not mention running light or while shoving a cut while serving an industry

 F10 Class Lights

If you have our FP9A locomotive, you might be wondering why the GMD-1 only has

white class lights. Green class lights mean a second section is following. Red class lights

mean the engine is pushing a passenger train. While we would love to see the GMD-1

hauling the Super Continental during the Expo 67 rush or pushing GO trains in commuter

service, these events are not entirely likely. So we just put in the white class lights.

 

When you press F10, all the class lights come on.

Red markers would not be used simply for shoving operations as part of switching. You only use them on the rear end of a train on the main line.

Chris, thank you. That's good news too. I can replace the entire three LED installation with single brighter LEDs for front and rear lights.
