Traffic Light Needs Updating

So, you're headed south on 27th by the Double Tree Inn. The light turns red and all of a sudden a train start rolling through, turning the traffic light red for all traffic in every direction.

It would be nice if they would update that light with a green arrow to turn left (or east) for those folks who shouldn't be held up there unnecessarily.

I mean we've got new traffic lights up in some parts of town with yellow arrows, which apparently mean different things than just plain old fashioned, green, non-flashing arrows.

This is confusing to us old people. I hope they fix this.
