The Reading 2100 was built in 1923 by the Baldwin Locomotive Works, and was originally a 2-8-0 and was numbered #2020. It was rebuilt in 1945 and converted to a T-1 class, 4-8-4 by the Reading RR. It was retired in 1964, and sold to a Baltimore scrap yard, where I found it in 1977. It somehow survived, was sold a number of times, was restored, and is now owned by the Golden Pacific RR in Tacoma, WA.
