If a train length is 200 meters, what would be the holding test duration?

In railway operations, the holding test duration is typically calculated based on the length of the train and is often expressed in a specific time format. For a train that is 200 meters long, the standard holding time is determined by a formula or guideline set by railway authorities, which typically outlines the time needed for operational considerations, such as ensuring safety and allowing for any required operational checks.

In this scenario, if a train length of 200 meters corresponds with a holding test duration of 13 minutes, it suggests that this is the recognized standard for that particular length of train. This duration allows for the necessary safety protocols and checks to be carried out effectively without exceeding the time needed for those specific operational requirements.

Other options that suggest longer durations may not align with the practices specifically designated for a 200-meter train length, which indicates that the correct answer is based on established regulations or guidelines within the context of New South Wales railway operations.
