When do SEPTA passenger trains with two or more cars need to have the first two cars open?

The requirement for SEPTA passenger trains with two or more cars to have the first two cars open at all times ensures accessibility and convenience for passengers. This practice is particularly important for maintaining the flow of passenger boarding and alighting, improving safety, and accommodating heavy passenger volumes, especially during busier travel times. Keeping the first two cars open allows passengers immediate access to the train and facilitates a smoother experience, whether during peak hours or at any other time, ensuring that the service remains efficient and user-friendly throughout the day.

Other scenarios presented, such as only during peak hours or late at night, could lead to inadequate service levels during less busy times, while conditions like rain should not dictate operational policies concerning train car accessibility. Overall, the requirement is designed to promote consistency and reliability in service for all riders.
