Has Caltrain changed the behavior of their signals?

I never noticed this before, so I think this is new - the following two photos show the signals at the Castro Street crossing in Mountain View.

If you look closely, you will see that the signals are dark in the first picture:

But a couple of minutes later, with a train approaching (and the sun is out, too, but I doubt that that is the reason :-) ), the signals are now showing aspects:

Now I’ve seen this elsewhere before, but not on Caltrain. Or did I just never pay attention?

Interesting. Are these tracks CalTrain owned, or a freight right of way? Are they shared at all?

They are Caltrain owned, but UPRR operates freight trains over them.

This seems very odd to me, but then I am accustomed to the signals on the NEC, and they are lit all the time.
