Track warrants are used to prevent what risk?

• A. Weather delays
• B. Mechanical failures
• C. Staffing shortages
• D. Potential collision risk

Answer: (D)

Track warrants provide explicit authority for a train to occupy and move over a defined section of track, coordinated by the dispatcher. This creates an exclusive movement window on that route, so another train cannot be granted authority on the same block at the same time. By establishing who can be where and when, track warrants prevent two trains from entering or occupying the same track section and risking a collision. Weather delays, mechanical failures, and staffing shortages are separate issues that warrants don’t directly address; warrants focus on coordinating train movements to mitigate collision risk.
