The Danbury Railway Museum (reporting mark DRMX) is a railway museum housed in the former Union Station on the east end of downtown Danbury, Connecticut, United States. It was established in the mid-1990s following the closure of the station by the Metro-North Railroad in favor of a new station nearby, and primarily focuses on the history of railroading in southern New England and neighboring New York. In addition to the former station building, the museum has a collection of heritage railcars in the neighboring rail yard it shares with Metro-North.
