The station was renowned for its architecture but cursed for inundating the heart of the city with the smoke and noise of the day's steam locomotives. The Chinese Wall also made Center City north of the station unfashionable, as the area was cut off from the rest of downtown. Passengers arriving at Broad Street Station could make connections to the rest of the city on the numerous trolley lines on Market Street and 15th Street, or on Philadelphia's east-west Market-Frankford Subway-Elevated Line (beginning in 1907) or the north-south Broad Street Subway starting in 1928. The latter two were heavy rail lines that crossed under City Hall.
