The Newburgh, Dutchess and Connecticut Railroad was a railroad in Dutchess County, New York, United States. Its line ran 58.9 miles (94.8 km) northeast from the Hudson River in Fishkill to the Connecticut state line near Millerton. The Dutchess and Columbia Railroad (D&C), was chartered in 1866 to link rural villages with the Hudson River Railroad and New York and Harlem Railroad. The under-construction line was leased by the Boston, Hartford and Erie Railroad (BH&E) in 1868. The first segment opened in July 1869, and it reached Pine Plains the following February.

The New York and New England Railroad (NY&NE) was a railroad connecting southern New York State with Hartford, Connecticut; Providence, Rhode Island; and Boston, Massachusetts. It operated under that name from 1873 to 1893. Prior to 1873 it was known as the Boston, Hartford and Erie Railroad, which had been formed from several smaller railroads that dated back to 1846. After a bankruptcy in 1893, the NY&NE was reorganized and briefly operated as the New England Railroad before being leased to the competing New York, New Haven and Hartford Railroad in 1898.
