As a post office with supra-regional responsibilities, this type of facility combines a strong focus on serving the public and proximity to the city with a section of the operation entirely dedicated to the rapid, efficient, and economical distribution and handling of large volumes of mail. The location of such a post office should be chosen to allow for direct access to the train station and its passenger platforms, as well as the availability of a separate mail loading track. Furthermore, the main highway must be easily and quickly accessible for mail exchanges involving motor vehicles. In addition, such a high-traffic post office should be located in the immediate vicinity of the city's commercial centre and connected to it by good pedestrian walkways.
