THE BASILICA OF CONSTANTINE, ANYONE? Live from the Third Rail links to coverage of the design for the new World Trade Center tube station at Hudson Terminal. The designer is Santiago Calatrava, who conceived the racing sailboat (?) at Milwaukee's lakefront Art Center. The article reports that the design will shine natural light down to track level, 60 feet below the street. Mr Calatrava could do worse than to pay tribute to the trainshed at Penn Station, which in its original form had lots of natural light down to track level.
