There is a Facebook Page for all kinds of things, including the ever popular caboose: https://www.facebook.com/groups/RRcaboose/
I could not resist joining the group and will share some of my caboose photos. Here is a copy of my first post:
I found this Page while doing some research and could not resist joining and sharing a few of my old photographs. I am a photographer and writer and have through the years produced three RR books based on my photographs. Here is one of my favorites images, it appears the the caboose is being steered, but of course it is going down a slight incline and the brake is being applied as it reaches its destination. This was taken at the Western Maryland Railway facility in Hanover, PA, circa 1972.
