A new documentary airing on PBS gives some flesh to the ghost of New York City’s original Penn Station.

A new high-speed train complex in Bengbu is nearing completion. Designed by Shanghai-based Verse Design, the two six-story buildings bracket an existing train station, which opened in 2011, and define the north and south sides of the new plaza.

This grand station serves as an intermodal hub for intercity trains, local rail lines, taxis, buses, and private cars. But with its enormous circular roof and glass drum, it also acts as an important landmark for the southern part of Shanghai and a symbol of a city that seems to be always on the move.
