Brooklyn Electrification: Reflective of National Trends and Practices [History]
Brooklyn became part of the city of New York (Greater New York) on 1 January 1898. However, the fact that it once was a separate city, with its own government, commercial enterprises, press, culture, and entertainment centers, remains a factor in both civic and technological areas. For example, the present day subway system evolved along two separate concepts with different sizes of vehicles and variations in signal components. Similar differences impacted the evolution of Brooklyn?s electrical generation and distribution system.
