There is a rumor circulating that Pan Am Railways, the host railroad of the Downeaster service between Boston and Brunswick, ME, is for sale. If you recall, in the planning stages for the service, the railroad was not a friendly player. They were strongly opposed to running trains on their tracks at 79 MPH, although that speed is hardly attained anywhere--if at all--these days. The issue was eventually settled, and I would think that 70 MPH is the top speed that the service makes.
