Reflecting on the Northern Lights Limited! On the evening of Saturday, December 16, 2017 at Railroad Museum of New England, we catch former New Haven (2049)/Penn Central (5049)/Conrail (5049)/MTA Metro-North Railroad FL-9 2019 in push mode as a sold out holiday train returns to Thomaston, CT while passing over the Naugatuck River. This unit has been in the hands of several owners over the years, and is still a beloved classic as it approaches 60 years of age.
