At what speed should trains operate in most urban terminal areas to ensure passenger safety?

In most urban terminal areas, trains should operate at a speed of 15 MPH to ensure passenger safety. This speed is regarded as a standard limit because it allows for swift yet safe navigation through densely populated areas where pedestrian traffic is significant and emergency situations must be managed effectively. Operating at this moderate speed enables train operators to maintain better control of the train and makes it easier to stop quickly if necessary, thus prioritizing the safety of passengers boarding and disembarking as well as individuals in the vicinity of the tracks. Moreover, the lower speed limit helps facilitate interactions with the environment, including other vehicles and pedestrians, ensuring a more secure operating condition in urban settings.
