After outcry over the hours for a series of public hearings about a plan to raise fares on Metro North's New Haven Line, the times have been doubled.  Wilton Senator Toni Boucher, a ranking member of the legislature's Transportation Committee, says she's hearing an earful from her constituents who depend on the train to get to and from work who weren't able to make it to daytime sessions.  The plan calls for a 5-percent hike in December to help balance the State Department of Transportation's budget.  None of the hearings scheduled for September are in the Greater Danbury area.  The closest is Waterbury on September 13th.
