Reflectors Nailed to Ties; Purpose? - Model Railroader Magazine

Don't know, Ed.    VR has a cam in WI., that's the only one I watch.

This in California, so who knows what they are about!  Maybe soem of our freinds on here from CA knows.

I've never noticed or seen them at any Amtrak stations around here, in WI.  I've been the Hiawatha trains many times.  (Chicago/Milwaukee)

I like your idea, about seeing something on the tracks.

Mike.
