The chosen location was occupied by an open-air market that had been in continuous operation since 1853. After loud complaints and much negotiation, the railroad agreed to purchase the markets for $1 million and move them to a new structure: the Reading Terminal Market, located to the rear (north) of the headhouse at 12th and Filbert Streets. This required the trainshed and all of its tracks to be constructed one story above street level, with the Ninth Street Branch to bring trains in and out.
