Which statement is correct regarding closing train doors on passengers too quickly?

The statement that closing train doors on passengers too quickly does not help shorten station stop time is correct because rapid closing of doors can actually have the opposite effect. When doors are closed too quickly, it may lead to passengers being caught or delayed as they struggle to board or disembark. This can result in additional time spent managing these situations, requiring the train operator or staff to intervene or delay departure to ensure passenger safety. In contrast, a measured approach to closing doors allows for a smoother flow of passengers, ultimately contributing to better adherence to scheduled stop times and operational efficiency. Moreover, a hasty closing of doors can compromise the overall safety of passengers, as it may not adequately accommodate those who are trying to enter or exit the train.
