North Philadelphia continued to grow during the early 20th century as a popular residential area for the nouveau riche rejected by old money society. Two ballparks (the Baker Bowl and Shibe Park) were located nearby, as were new cultural institutions and automotive industry buildings. In 1928, the Broad Street Subway was opened with a station at North Philadelphia, offering more frequent service to Center City. Its northern entrances were located at the intersection of Glenwood Avenue and North Broad Street, with an underground passage offering an easy connection to the PRR station. The Reading Company replaced Huntingdon Avenue station with North Broad Street station, a massive Classical Revival structure rivaling the PRR station in grandeur. 30th Street Station opened in 1933, reducing North Philadelphia's importance for north-south services. However, North Philadelphia continued to serve heavy commuter traffic and east-west long-distance trains.
