? What do you mean "wool's" ?

 

Spell checker or my fingers got me.

Wolo horns?

 

Yes, they are the Wolo train horns. They were the best I could find that would fit as they do not use an air compressor. I really wanted a true train horn but there was no room for the tank and air compressor since I installed the refrigerator, color laser jet printer & binding machine in the trunk...

 

I need those for my neighborhood.
