What is the most serious consequence of not allowing enough time for passengers to enter and exit the train?

Not allowing enough time for passengers to enter and exit the train can lead to passengers being hurt, which is the most serious consequence of this oversight. When the train doors are closed too quickly, there is a risk of passengers being trapped in the doors or falling as the train begins to move. This situation can result in injuries ranging from minor bumps and bruises to more severe accidents that could cause significant harm. Safety is the foremost priority in train operations, and ensuring that all passengers have safely boarded or disembarked before closing the doors is crucial for preventing accidents and protecting passengers.

While delays in the schedule, passenger discomfort, and increased wear on doors are important considerations, they do not carry the same level of immediate risk to passenger safety that mishandling the entry and exit timing does. The potential for injury is a grave concern and underscores the importance of well-managed boarding and deboarding procedures.
