What should be ensured about the good section while moving the train from the live section?

Ensuring that the good section has an equal or greater number of cars when moving the train from the live section is crucial for maintaining the stability and balance of the train during the transition. This practice is essential to prevent any potential derailments or accidents that could arise from an uneven distribution of weight. If the number of cars is insufficient, it can lead to an imbalance that affects the train's handling, especially as it moves from one operational section to another.

In train operations, maintaining balance is vital for safety, especially during movements that involve changing from one section (like a live or powered segment of the track) to another section. The dynamics of train movement can be significantly impacted by the distribution of weight across the cars, which is why ensuring an equal or greater number of cars in the good section helps provide the necessary stability.

Other factors, such as direction, safety equipment, or testing for speed, do play roles in overall train operation safety but are secondary to the immediate concern of maintaining the correct number of cars for stability during these specific operational maneuvers.
