The Dispatcher may verbally authorize movement against the current of traffic at an interlocking. The movement is limited to how many train lengths beyond the home signal?

• A. One train length beyond the home signal
• B. Two train lengths beyond the home signal
• C. Three train lengths beyond the home signal
• D. The next signal

Answer: (A)

When the dispatcher verbally authorizes movement against the current of traffic at an interlocking, the train may proceed only a short distance—specifically, one train length beyond the home signal. This limit creates a defined, easily controlled protection zone you can observe and stop within if a conflicting movement occurs. The home signal marks the entrance to the interlocking, and limiting the movement to one train length beyond it keeps the operation safely within a short, protected distance. If more movement were needed beyond that point, a different form of authority or signaling would be required.
