I'm looking for a guidebook, website or other reference source that interprets and describes the uses, functions and placement of the multitude of static, trackside railroad signs and their symbols found on the prototype across the U.S. If they happen to be line-specific, I model the Great Northern in the transition era. I found no such information on the GNRHS site.
What do you recommend?
Thanks.
