HARTFORD - Lawmakers are demanding answers following a series of problems that disrupted service on Metro-North last week.
Close to 200 passengers were stranded on a train without heat in Westport Wednesday.
The next night, the New Haven, Harlem and Hudson lines were affected by a two hour power failure.

Metro-North has blamed that problem on a mistake made by a maintenance crew.
Gov. Dannel Malloy says there is no reason that work should have been done during the evening commute.
The MTA has said action is being taken to determine why those mistakes happened and to prevent them from occuring again.
