When a station name designates the last named point on a track warrant, how far does the authority extend?

• A. To and including the first switch at last named point.
• B. To the next station
• C. To the end of track
• D. To the last-mile marker

Answer: (A)

In Track Warrant Control, the boundary of authority is defined by the last named point plus the first switch at that point. So when the last named point is a station, the train’s authority extends to and includes the first switch located at that point. This switch marks the actual boundary between blocks, so movement up to and through that switch is covered, but anything beyond that switch requires a new or additional warrant. Other interpretations—such as stopping at the next station, the end of track, or a mile marker—don’t reflect how warrants delineate limits with the boundary defined by the switch at the last named point.
