c.1877 Three 10 HP hot air engines were supplied by A. and F. Brown of New York to drive the generators for the light and the air compressors for the fog signals. The flywheels were 8 ft 6" diameter and ran at 60 rpm.

The fog siren, which produced a 'weird and melancholy' sound, was designed by James Douglass and George Slight of Blackwall.
