Gov. Deval Patrick, U.S. Rep. Richard E. Neal, D-Springfield, U.S. Rep. James McGovern, D-Worcester, and retired U.S. Rep. John Olver of Amherst hosted dignitaries and press on the "Knowledge Corridor Special." It was a test run of passenger service on tracks rebuilt in a $120 million state and federal project. The federal stimulus program provided $73 million of the $120 million, with the state making up the rest. The trip was also an old-fashioned whistle-stop with politicians de-training in Holyoke, Northampton and Greenfield for speeches and well-wishes. Northampton even had a marching band.
