Cos Cob Power Station, Electric power station in Cos Cob, Connecticut, US.
The Spanish Revival style power station stood near Metro-North Railroad tracks, the Mianus River, and Sound Shore Drive in Greenwich, Connecticut.
Constructed between 1905 and 1907, the facility became the first power plant in the United States specifically built to supply mainline traction power to railroads.
The station name originates from the Coe family, who built a protective wall called a cob near their settlement in 1641 in this Connecticut region.
The power station supplied electricity to multiple railroad companies including New Haven, Penn Central, Conrail, Amtrak, and Metro-North from 1907 until 1986.
The facility pioneered alternating current electrification technology, enabling trains to switch between third-rail DC system and AC system on main lines.
