The now Hybrid wigwag on Van Ness Ave in Fresno CA. No audio.

The crossing covered by the Van Ness wigwag has a blind approach (for both the train crew and automobiles) going south down the street. Train building from the nearby yard means lots of back and forth movements on the line, which fouls the crossing numerous times. There really isn't another location...

The Van Ness signal was turned hybrid as well. The banner survives, but is not functional

At first the banner survived, but was not functional.
