What characterizes "Express Service" on SEPTA?

Express Service on SEPTA is primarily characterized by its operation that makes fewer stops along its route compared to local services, allowing for faster travel times. This type of service is designed to cater to commuters looking to reach their destinations more quickly, particularly during peak travel times. By skipping certain stops that local services typically make, Express Service can significantly reduce overall travel time for passengers traveling between major hubs or densely populated areas.

While there are services that operate at night or are focused on long-distance travel, these aspects do not define Express Service. Reservations typically do not apply to express services in standard operations, as the focus is on providing accessible and quicker transit options for the general public without the need for advanced booking. Thus, the defining characteristic remains the speed and efficiency offered through fewer stops along the route.
