Encased in wrappings, as well as history, Penn Station’s face lift begins

Charles Street’s Pennsylvania Station is now wrapped in scaffolding and a dark filmy safety material that makes the building pop out. It’s open for business and in the first six months of a planned transformation and expansion designed to make this landmark more of a neighborhood anchor than it already is. Workers now are repointing its stone walls and checking for structural stress that the historic structure may have suffered during its lengthy existence.
