If a train has a crew member preceding the reverse movement, how far may the reverse movement go?

When a train has a crew member preceding the reverse movement, the correct limit for the reverse movement is up to the last whole mile post or station. This practice ensures safety and clarity in operations, as it allows the train to reverse without exceeding established limits and ensures that the crew can adequately supervise the movement.

The specific reference to the last whole mile post or station provides a clear and measurable endpoint, helping to prevent potential accidents and miscommunications. It aligns with standard practices in rail operations, where defined distances and landmarks are critical for maintaining safe conditions.

Other choices do not adequately define a safe operational limit. Moving beyond the nearest whole mile post is ambiguous and may lead to unsafe situations. Allowing the reverse movement only to the next station could be too limiting and does not account for operational scenarios. Limiting the movement to half a mile back does not consider the existing mile posts or stations, which provides clearer operational direction. Thus, the option that includes the last whole mile post or station is the most precise and aligned with safety protocols.
