RR Museum of Pa. has changed policy. Last time I published photos from them, it was permissible with mention of them in the caption. Now it seems they want $25 for each time a photo is published, and it is not clear whether that is $25 for each time it appears in a magazine, or for each time the magazine copy rolls off the press. It would be nice if they did not care about internet publishing, but I think I would check.
Harold Vollrath still allows free publication - what a nice guy, and a fellow hobbyist.
