Recently some of our newer museum members were asking about the restoration the museum did on ex-Penn Central Railroad transfer caboose #18526. Donated in 1996 by Conrail, the caboose was restored both inside and out between 1998 and 2002. At the time of the donation, the #18526 was complete, but had been in a roll over accident where it rolled on to its side on an adjacent track causing a large crease in the side of the car and jarring loose many interior fixtures.
Here is a Flickr album of the caboose as it was delivered, during the restoration process and completely restored inside and out including interior photos taken just recently.
