The first company that would later become part of the Newburyport Railroad was the Newburyport and Bradford Railroad, incorporated on March 11, 1846. It opened a line from Newburyport on the Eastern to Georgetown in 1849 and extended it west to the B&M at Bradford in 1851. The second company, the Danvers and Georgetown Railroad, was organized on May 7, 1851 and began work inApril 1853 on a line running from the Newburyport Railroad at Georgetown south to Danvers on the Essex Railroad. The third company, the Danvers Railroad, was incorporated on March 15, 1852, and began construction in August 1853 on a line from Danvers southwest to the South Reading Branch Railroad and the B&M in Wakefield. On October 23, 1854, the entire line from Newburyport to Wakefield was complete. On February 22, 1855, the first two companies merged to form the Newburyport Railroad, which operated the section from Newburyport to Danvers. The B&M operated the section from Danvers to Wakefield, and in 1860, it leased the Newburyport Railroad, taking over operations on the entire line and running it as its Newburyport Branch. On October 30, 1906, the B&M bought the line outright. After World War I, the Newburyport Branch experienced a decline in ridership, and in 1924, the B&M tried to end service, but passenger and industry protest kept it open. In 1940, the B&M successfully applied to close the line between Newburyport and Topsfield, and service ended there in December 1941. The following year it abandoned the line between Georgetown and the paper mill in Bradford, servicing the paper mill from the B&M main line instead. In 1950, passenger travel ceased between Topsfield and Danvers, and in 1959, all passenger travel on the line came to an end. In 1976, the B&M sold the section from Wakefield Junction to Topsfield to the Massachusetts Bay Transportation Authority. In 1981, the section between Topsfield and Danvers was abandoned. Freight service continued on the section between Wakefield and Danvers until about 2001. The line served freight customers on the former Essex Railroad until a fire destroyed the Waters River Bridge, preventing freight traffic from continuing to Salem.
