Not only curious for myself but also if I need to explain it to someone from out of town.
Don’t turn right, when the sign is turned on, which happens when a train is approaching. When it’s off, it’s the same as no sign; when it’s on, it’s the same as a normal printed metal sign.
In some places it effectively means “red means red”, where a right turn, normally legal, would cross the tracks. I think Erb eastbound at Caroline is like that.
In other places, it means the right turn, normally permitted because the light is green (or there is no signal), is not safe due to a train. I think Caroline southbound at William is like that.
(in both locations I can’t actually remember for sure if there are signs of the type under discussion)
