What happens to the Rules-in-Effect on an out-of-service track?

The correct answer highlights that specific rules, such as ABS (Automatic Block Signal), CSS (Cab Signal System), DCS (Dispatcher Control System), and Interlocking rules, do not apply to an out-of-service track. This is significant because when a track is designated as out of service, it is not intended for regular train operations and may have different safety and operational requirements.

In this context, the exclusion of these specific rules reflects an understanding that the standard operating procedures associated with movement on active tracks, which include signal systems and interlocking mechanisms, no longer hold the same authority or relevance. The safety of train operations relies on the assumption that regular signals and interlockings guiding train movement are not in effect, thus affecting how crews are required to approach the out-of-service track.

This information is critical for ensuring that railroad personnel operate under the correct assumptions regarding the status of the track and apply appropriate safety measures in accordance with the established guidelines for out-of-service track conditions.
