The Connecticut Western Railroad was chartered June 25, 1868 to run from Hartford, Connecticut west to the New York state line, where it would meet the Dutchess & Columbia Railroad just east of Millerton, New York. The line was completed December 21, 1871; the previous month the company had leased the easternmost bit of the D&C to gain access to the New York & Harlem Railroad at Millerton. The only branch was a short one in Connecticut, south into Collinsville, which would not be completed until December, 1874. The Connecticut Western became bankrupt on April 27, 1880, and on March 31, 1881 it was reorganized as the Hartford & Connecticut Western Railroad.
