Their web site is uninformative; for an organization that builds around "Railroad Town", they don't do a very good job of talking about their railroad holdings. The article seems to say that they would junk stuff only if they couldn't find another home for it, but I'm not sure how they plan to go looking for a home. Any railroad operators who are reading this might want to contact the museum directly
info@stuhrmuseum.org">(info@stuhrmuseum.org) to express an interest in receiving excess equipment from them.
