Engraving from the cover of Scientific American April 2, 1881 issue depicts Charles F. Brush dynamos. Belts delivered power from the reciprocating steam engines in a lower floor. Beginning operation in December 20, 1880 at 133 and 135 West Twenty-Fifth Street, it powered a 2 mile long circuit consisting of 15 arc lights strung along Broadway from 14th to 26th street. Two weeks later, the line extended to 34th street. Each light had a shunt so that if a light exhibited high resistance, the shunt would close and current would continue to other lights on the line. source Each generator produced 10,000 volts. source
