Waterbury Branch

Metro-North Railroad's Waterbury Branch is a branch of the New Haven Line, running north from a junction in the Devon section of Milford to Waterbury. Originally built as the Naugatuck Railroad, it once continued north to Winsted. The part north of Waterbury is now leased from CDOT by the Railroad Museum of New England, which operates excursion trains from Thomaston station through their operating subsidiary Naugatuck Railroad ; this name was chosen in homage of the original railroad. The trackage ends in Torrington but Metro North service on the branch ends at Waterbury. There are conceptual plans to extend service from its current terminus in Waterbury to Hartford via Bristol and New Britain. Except for one weekday off-peak train that operates from Stamford to Waterbury, all trains on this branch operate as shuttles between Waterbury and Bridgeport.
