A woman was struck and killed by a Boston-bound Acela train passing through Attleboro around 1:20 p.m. Wednesday, officials said. The woman was struck on tracks near Newport Avenue and the South Attleboro train station, MBTA spokesman Joe Pesaturo said. The tracks are owned by the MBTA, and MBTA Transit Police are investigating. Amtrak Acela Express Train 2154 originated in Washington, D.C., and was carrying 197 people. None of the passengers or crew were injured, said Amtrak spokesman Cliff Cole. Pesaturo said delays were expected for Amtrak service in the Northeast Corridor and for the MBTA’s Providence/Stoughton commuter rail service, which runs on the same tracks.
