    • Approach home signal prepared to stop,
    • Not exceed 40 MPH unless governed by a slower speed, AND
    • Resume the speed authorized by the distant signal when the home signal is seen to display a proceed indication
    • ref 504.9b
  11. You pass a Clear indication on a signal governing the approach to a railroad crossing at grade. If your train speed is reduced to 15 MPH after passing the Clear signal, how must you approach the signal at the railroad crossing at grade?
    • Prepared to stop
    • ref 504.9a
  12. What authorization is needed to open a switch to a signaled track?
    • Signal Indication, or
    • Permission of Train Dispatcher
    • ref 504.13
  13. You have been given permission to take the power-operated switches off of power and place them in hand operation. How may you operate by the Stop signal that governs the switch?
    • Can go by Stop signal without permission at Restricted Speed
    • ref 504.15
  14. After restoring the switches to motor or power position, how may a train proceed?
    • Signal Indication, or
    • Permission of the Train Dispatcher
    • ref 504.15
  15. If a train has permission of Train Dispatcher to make a reverse movement within limits of the same block, how must the movement be made?
    • Restricted Speed with a crewmember located on the rear of the movement
    • ref 504.16
  16. How can a train make a reverse movement within the limits of the same block without permission of the train dispatcher?
    • Restricted Speed, AND
    • A crewmember or other qualified employee is positioned on the ground ahead of the leading end prepared to stop any opposing movement
    • ref 504.17

    • ref 504.19
  19. What must you have in order to pass a Stop Signal?
    • Permission from Train Dispatcher
    • ref 504.21
  20. Can you pass a stop signal without permission of Train Dispatcher when necessary to recouple to your train located immediately beyond the signal and no power operated switches are involved?
