BRIDGEPORT, Conn. (AP) - Investigators will look closely at a broken section of rail to see if it is connected to the commuter train derailment and collision outside New York City that left dozens injured. Meanwhile, the focus begins to shift toward cleanup and rebuilding ahead of challenging times for travelers and commuters along the Northeast Corridor.
    
A member of the National Transportation and Safety Board says that a fractured section of rail is of substantial interest to investigators and a portion of the track will be sent to a lab for analysis. Officials also said Saturday the incident was not the result of foul play.
    
The crash of the two Metro-North trains damaged the tracks, snarling travel in the Northeast. The crash caused Amtrak to suspend service between New York and Boston.
    
Connecticut's governor says commuters should make plans for alternative travel through the area.
