Here's an interesting warning device for emergency vehicles. It's a
Harpes wigwag, used to stop traffic as emergency vehicle enter the street.
Dave Hudson stumbled across this on a recent railfanning trip through West Chicago.
He explains more here...
When I did come back I realized that the flagman isn't protecting a railroad crossing. It would appear that it warns traffic about emergency vehicles leaving the fire station. I was a bit behind schedule, so I wasn't able to quiz the firehouse staff about it. There is a plaque on the mast that indicates it was donated by a private individual in 1975.
I've included several pictures of the unit and my usual Garmin map of the location.
Oh, the fire station's address in West Chicago is 200 Fremont St."
