Hartford and New Haven Railroad

The Hartford and New Haven Railroad (H&NH) was an important direct predecessor of the New York, New Haven and Hartford Railroad. Its railroad commenced service in 1844 and ended independent operations in 1872. The main line from New Haven, Connecticut to Springfield, Massachusetts remains in Amtrak service.

The Hartford and New Haven Railroad of Connecticut was chartered in 1833 to build a railroad between Hartford and New Haven. The grandfather of J. P. Morgan was an original investor, laying the foundation for the long association between Morgan and the railroads of New England. It commenced full operation in 1839, with half of the line opening the prior year. The Hartford and Springfield Railroad was incorporated April 5, 1839, and built the Massachusetts portion of the Hartford-Springfield route, which opened in 1844. The New York and New Haven Railroad was incorporated in 1844.

In 1845, the Hartford and New Haven merged with the Hartford and Springfield Railroad to form the New Haven, Hartford and Springfield Railroad. This new railroad changed its name to the Hartford and New Haven Railroad in 1847.

The Hartford and New Haven and the New York and New Haven were consolidated into the New York, New Haven and Hartford Railroad in 1872.

The steamship lines of Long Island Sound had the capability of offering all-water service to Hartford via the Connecticut River. The New Haven and Northampton Company had the right to build from New Haven to Springfield on an old canal and completed construction from New Haven to Plainville, Connecticut. In cooperation with the New York and New Haven Railroad it would have been able to offer all-rail service parallel to the H&NH. It was this threat that led to 18 years of controversy and litigation, culminating in the consolidation of the two lines in 1872. For some years, the resulting line was known as "the Consolidated".
