New York, New Haven & Hartford Railroad, Bridge-Type Circuit Breakers, Long Island shoreline between Stamford & New Haven, Cos Cob, Fairfield County, CT

Significance: These circuit breakers provide electrical fault protection for individual track sections of the Metro-North power transmission system. They are integral components of the first long distance railroad electrification project built in the United States. Although they were modified in 1914 and 1942, their basic design has remained the same over eighty-seven years of relatively trouble-free service. They are a prime example of functional and adaptable engineering design and construction.
