 Those stations were completed and in operation by 1933, but a number of factors, including the Great Depression which stalled the planned redevelopment, forced the railroad to continue utilizing Broad Street Station for certain types of trains (such as the Philadelphia-New York "Clockers", and steam-powered trains of the Pennsylvania-Reading Seashore Lines) for nearly two more decades.Broad Street Station was not completely vacated until 1952, during the term of Mayor Joseph S. Clark.Plans for the demolition of the Chinese Wall and accompanying train station were finalized and both were razed in 1953.
