The Waterbury Branch is a branch of the Metro-North Railroad New Haven Line, running north from a junction in the Devon section of Milford to Waterbury, Connecticut. 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. Currently, riders that want to continue to New Britain and Hartford have to transfer to an express bus operated by CTtransit at Waterbury. All trains on this branch operate as shuttles between Waterbury and Bridgeport. The Waterbury Branch currently uses 2 trains to run up and down the branch simultaneously providing 22 daily trips on the branch with large turnaround times sometimes consisting of 90 minutes or more, this will be revised to add additional trains once ridership allows. All platforms currently consist of low-level platforms with the exception of the terminal stations being Bridgeport and Waterbury. A new station consisting of a high-level platform at Derby-Shelton is currently awaiting construction while new station plans at Ansonia, Seymour, Beacon Falls, and Naugatuck are currently awaiting designs and funding. For most of its route, the branch runs parallel to the Naugatuck River, viewable on the right side northbound and the left side southbound. History In 1906, work on double-tracking the branch between Seymour and Waterbury was underway. It was completed in 1907. In September 2015, it was announced that out of Governor Malloy's 30-year-$100 billion transportation plan, $350 million has been included to improve service along the branch. The upgrades include a new signal system with multiple passing sidings to increase service, newer equipment, and station rehabilitation. Currently, only one train is allowed on the branch at a time. The signalization of the line will allow for multiple trains to safely be on the branch at a time, while allowing for increased capacity and safer train operation. Four passing sidings at Devon, Derby, Beacon Falls, and Waterbury will be built, and they were expected to be completed in 2018. Work began on a siding just north of
