Seashore acquired No. 100 when York Utilities ceased operation in 1949. No. 100 received little attention at the museum until Seashore began planning a restoration in 1999. In 2006, Seashore received Federal Transportation Enhancement funds which paid for a significant part of No. 100?s restoration. To comply with the restoration grants, the museum searched for and used original materials such as southern yellow pine. No. 100 arrived at Seashore painted green, but careful scraping revealed that the locomotive was brown during most of its life. In 1980, the National Park Service placed No. 100 on the National Register of Historic Place along with nine of the museum?s other Maine cars.
