Beginning on May 24, 2004, construction of new platforms began at Clinton, Guilford, and Branford. The rebuilt Clinton station opened on July 25, 2005, and the rebuilt Branford station opened on August 8, 2005; both consist of a single high-level platform on the south side of the tracks. The new Guilford station, which has platforms on both sides of the tracks (connected by a pedestrian bridge) to allow for greater operational flexibility, opened on November 28, 2005. Construction at Madison started on September 24, 2007, and finished with the opening of the rebuilt station platform on July 28, 2008.
