Assuming you don't work for the RR or the leasee of the property, I would assume you would be responsible enough to stay off the equipment and property, much less advertise it on an internet forum. If ya do work on the property, there should be no problem accessing the equipment. Please practice responsible railfanning and don't go where ya don't have to be. Besides, if you were spotted on the equipment, it becomes a FEDERAL trespassing charge as well as the local laws being applicable, as railroads are federally regulated. Don't make things more difficult then they already may be, at least for any other fans in the area!
I know I'm getting old... My insurance company sent me only half a calendar this year!
