About Video #823

This video shows the “TWO-BUTTON” system where the public can push and hold a ‘Forward’ button to make the train move in the forward direction, or push and hold a ‘Reverse’ button to make the train move in the reverse direction.

This system has 3 “modes” of operation:

  • Mode 1: The public can HOLD DOWN either a “forward” or “reverse” button to control the train themselves.
    • The train will not move unless one of the 2 buttons is held down.
  • Mode 2: You can give the public a single button they can PUSH & RELEASE, that causes the train to automatically make 1 complete forward-reverse cycle by itself.
  • Mode 3: The operator can close a switch, that causes the train to run CONTINUOUSLY point-to-point automatically.
  • Note: Previous Video #822 has an “S Ga. Preview” of the two button system operating (a “forward” and a “reverse” button that the public could control), at this link:    (this link takes you to the 26:30 point in the video)
