At Dilworth Park a specially commissioned work of public art created by internationally recognized artist Janet Echelman will be integrated into the programmable fountain and will trace the path of trains traveling on the three lines below the park in real time, coded to the colors associated with each transit line. Thin columns of dry mist will emanate from the fountain, evoking the steam that rose from the city's first water-pumping station that was located on this site as well as the steam from the trains at the Pennsylvania Railroad Station that was located across the street. Echelman's use of dry mist enables people to walk through the installation without getting wet. A description of the installation, including a simulation of this work of art, entitled Pulse, may be found on the artist's website. For more information about Dilworth Park, visit DilworthPark.org.
