Service on the northern half of the Broad Street Line, between City Hall and Olney Avenue, opened on September 1, 1928. While the original subway tunnel had been finished to just north of the present-day Lombard-South station, service to the Walnut-Locust station did not begin until 1930; the Lombard-South station entered service in 1932. Service from that point south to Snyder Avenue began on September 18, 1938. Service to a new park-and-ride station built next to the Fern Rock shops began in 1956, and the line was extended further south to Pattison Avenue in 1973 to serve the recently completed Sports Complex.
