Is there sufficient clearance along the outside walls in the Center City Commuter Tunnel for normal passenger movement?

The statement regarding sufficient clearance along the outside walls in the Center City Commuter Tunnel for normal passenger movement is classified as false. This indicates that, under normal circumstances, the dimensions and design of the tunnel do not allow adequate clearance for passengers to move safely alongside the outer walls. This lack of sufficient clearance is an important safety concern, as it can lead to potential hazards for passengers who might be close to the walls while navigating the tunnel during busy times.

In contrast, other options suggest scenarios or conditions under which clearance might be considered adequate, like during emergencies or depending on traffic, but they do not reflect the regular operational conditions found in the tunnel. Thus, noting that the situation is false highlights the need for careful passenger management and adherence to safety protocols in that specific environment.
