What procedure must be followed when doors used at Center City stations are not to be used at outlying points?

The requirement to make an appropriate announcement about which doors are available is crucial for ensuring passenger safety and smooth operations. When certain doors at Center City stations are not operational or accessible at outlying points, it is essential to communicate this information clearly to passengers. By making an announcement, the conductor informs all passengers of the specific doors they should use, preventing confusion and ensuring that everyone is aware of the proper boarding and alighting procedures.

This practice helps maintain efficiency and safety within the station and on the train, allowing passengers to make informed decisions without frustration or delay. Ensuring that the correct doors are identified and communicated helps to prevent accidents and facilitates a smoother passenger flow, particularly important in busy transit environments.
