 Good evening. With this Maine Public Radio News, I'm Robbie Feinberg. Amtrak is installing a $50 million signal system on its tracks from Brunswick to Haverhill, Massachusetts, to improve the safety of both passenger and freight trains. Patricia Quinn with the Northern New England Passenger Rail Authority says the Downeaster continues to break records for ridership and needs the new technology to expand service. Right now, the Downeaster makes five round trips a day. We do have plans to go to a sixth.
