Notes
  • Significance: The Interlocking Control Building is significant because its console, relays and other internal components represent an early use of centralized train control on a major railroad. The console monitors and controls track turnouts and switches between Woodmont and Branford, Connecticut, a distance of nearly twenty miles. It was a large and expensive system for its time and made use of newly improved relay technology.
