The MTA is continuing to investigate a person being struck by a train on New Year's Eve.  Metro-North Railroad reported a person was struck on the tracks in Danbury Thursday night, near Taylor and Wildman streets. Train service was suspended on the line until about 12:35am.  The victim was only identified as a 30-year-old man.  The MTA says he walked through the crossing as the gates were down, bells rung and the train operator sounded a horn.  The man was transported to the hospital in serious condition with severe leg injuries.
