Lug nuts weigh heavily on minds of Newburyport/Rockport commuters

Seems yesterday's major delays on that commuter line were caused by what the Salem News called a stripped lug nut that kept the Beverly drawbridge in an open position for nearly four hours. The News also reports that repairs to the bridge begun in 2008 are still not finished.

So what about today's delays on the line? The T blames switch problems.
