How many tracks in Harrison Yard are equipped with derailers?

The question asked about the specific range of tracks in Harrison Yard that are equipped with derailers, which are safety devices used to prevent trains from entering a section of track where a potential hazard exists.

The correct answer indicates that tracks 5 through 16 are equipped with derailers, suggesting that these tracks have been designated for safety measures in operations within the yard. This likely means that these tracks require additional safety protocols due to their proximity to critical areas or operational functions that could pose risk without such equipment.

Understanding the importance of derailers in maintaining safety and preventing accidents is crucial for railway operations. Tracks that do not fall within this specified range (for example, the other answers mentioning different track ranges) would not have the same level of safety equipment, thus highlighting the importance of knowing which sections of the yard are secured.

Therefore, the reference to tracks in the given range reflects adherence to safety standards and operational protocols necessary for managing railway yard activities effectively.
