Several years ago had the opportunity to visit Steamtown located in Scranton Pennsylvania. It is a   railroad Museum  and heritage railroad at the site of the former Scranton yards of the Delaware, Lackawanna and western Railroad (DL&W). The museum is built around a working turntable and a roundhouse that are largely replications of the original DL&W facilities; the roundhouse, for example, was reconstructed from remnants of a 1932 structure. The site also features several working steam engines and exhibits.
