At the time this photograph was taken two copper cables were strung along this stretch of underground transit line that opened in September 1897. One or two power cables more were added a short time after 1901.

The tie wires employed were thick solid hard drawn bare copper, nearly the diameter of a dime and difficult to bend. As a result their cables were very tight and snug in their insulators' side grooves.

These lines were along the northerly side of the station's wall. The insulators and their conductors are long gone but the "crossarms" with their pins are still there to this day, exactly as you see them.
