.......................I don't think I've seen any photo's with the white wrapped chains but most of the photo's I've looked at are western.

 

Photo sample of a "Smile" chain, unit 599 in the northeast corridor.

 

I wonder now if white was used for better visibility of it. But they tended to grime up rather quickly.

 

Not sure, and just guessing but in looking at this photo, I'm thinking that 28 gauge electric wire comes close to the approximate thickness. What do you all think?  (credit to photographer)
