Which statement best describes occupancy within a warrant area?

• A. The train occupying the track segment under the warrant's authority is considered occupancy
• B. Occupancy refers to the signal position only
• C. Occupancy is the scheduled time window
• D. Occupancy refers to the maintenance crew's work area

Answer: (A)

Occupancy means a train is actually on the track segment covered by the warrant. The presence of a train on that segment defines it as occupied, and this real-time occupancy is what governs whether other movements can enter the same block. Signals and time schedules relate to movement control, but they don’t by themselves define occupancy. A block can be shown as occupied by a train even if the signal aspects suggest different possibilities elsewhere, and occupancy isn’t about a planned time window or about where maintenance crews are working. In short, occupancy is the actual physical presence of a train on the warranted track segment, which protects safe, orderly use of the block.
