Hi All not sure if any railway folk out there familiar with operations in the Powder River Basin hang around this forum but i sure would like to know what the green panel on that post means https://www.flickr.com/photos/ycsfsoya/36598717170/in/album-72157688488679155/ Pretty sure there is a mile post just to the right of that so if any one has any info on the green panel thingy I would be most grateful.
Cheers Mick.
