Poughkeepsie Bridge Route
The route specifically avoided the Port of New York, due to the lack of a rail crossing of North River (Hudson River). Instead it passed over the Poughkeepsie Bridge at Poughkeepsie, New York. Its Boston terminus at North Station, an advantage allowing for a direct transfer to Boston and Maine Railroad lines to the north.
The route used the following companies' lines:
- Baltimore and Ohio Railroad - Washington to Philadelphia
- Philadelphia and Reading Railroad - Philadelphia to Bethlehem, Pennsylvania (via the North Pennsylvania Railroad)
- Central Railroad of New Jersey - Bethlehem to Easton, Pennsylvania
- Lehigh and Hudson River Railway - Easton to Maybrook, New York
- Central New England and Western Railroad - Maybrook to Simsbury, Connecticut
- New York, New Haven and Hartford Railroad - Simsbury to Northampton, Massachusetts (via the New Haven and Northampton Company)
- Boston and Maine Railroad - Northampton to Boston (North Station) (via the former Central Massachusetts Railroad)
The route was only used from 1890 to 1893, after which operating patterns changed. Parts of the route near the Poughkeepsie Bridge have been converted to rail trails; the Hudson Valley Rail Trail to the west, and the Dutchess Rail Trail to the east. The closure of the bridge to rail traffic after a 1974 fire eliminated the route and created the Selkirk hurdle.
