Thomas Krens, who once directed the Guggenheim Museum in New York and its overseas satellites, on Saturday joined with the former Massachusetts governors William Weld and Michael Dukakis to announce an ambitious plan to establish a “cultural corridor” between North Adams and Williamstown, Mass.

The project, intended to draw more visitors to the northern Berkshires and to help the economy of North Adams in particular, would include a new contemporary art museum, the renovation of a 1938 movie palace and the building of what Mr. Krens calls a museum for “extreme model railroading and contemporary architecture,” all in or near North Adams.
