The PW&B started building its own station at the southwestern corner of President Street with Canton Avenue with train yards, including a roundhouse, shops and freight warehouses of about six square city blocks, extending east along Canton Avenue (later renamed Fleet Street). The Greek Revival-style station opened on February 18, 1850. In addition to the brick head house with a distinctive arched roof, the original station also had a long barrel vaulted train shed over the tracks. The PW&B added a similarly styled freight house, adjacent to the south of the passenger station, in 1852.
