Forgive me but I have a question on engine lights. I noticed that some modern era model engines have a yellowish-orange flashing light on the roof. It looks somewhat like an orange flashing light that you might see on top of a van or truck that's out doing electrical or road maintenance work. I think school busses have them now too, but they are more of a brilliant white color.
So here are my questions:
- What is this type of light used on these engines called?
- Are there specific engine operating rules for using this light (i.e. is to be lit at all times or only when the engine is in motion, in yard switching operations, etc).
- If multiple engines are joined together in a train, should all of the engines in the consist have this light on?
I have never seen this orange light on real engines, but unfortunately, I don't see too many engines in these parts.
