Here's an example not too far from where I grew up that I always found intriguing, though I'm sure there are similar cases that exist elsewhere. The intersection of PA 420 and Morton Avenue in Morton, PA has SEPTA's Media/Elwyn regional rail line running right through it. There are exclusive right/left turn lanes to/from PA 420 to South Morton Ave respectively, complete with traffic signals including right/left green arrows. Below are GSV links to the signals in question.

South Morton Avenue's signals

PA 420's signals

What I find interesting about these turn signals, is that they're only lit when a train is passing through the intersection. There is no advanced green for the left turn arrow for NB 420 traffic, nor is there a green arrow for Morton Avenue's counterpart during normal operation. The arrows are strictly used for railroad preemption, as turning traffic does not interfere with the crossing.

That's interesting. I've never seen that before.

Here's a neat one I just happened upon the other day, on Pioneer Road in an industrial area of western Salt Lake City.

The road traffic is controlled by traffic signals, which isn't too far out of the ordinary. But what's fascinating is it looks like even the train traffic is controlled by standard traffic signals, which I've never seen before.
