BRIDGEPORT - One of the engineers involved in last week's derailment and crash on Metro-North's New Haven line reported an "unusual condition" on the track before the derailment, according to federal officials investigating the crash.

The National Transportation Safety Board (NTSB) did not elaborate on what the condition was. The NTSB did say a joint bar used to hold two sections of rail together had cracked and was repaired last month.

Meanwhile, the first lawsuit connected to the crash has been filed. Attorneys for Elizabeth Sorenson, 65, are accusing Metro-North of negligence. Sorenson's lawyers say she remains in critical condition with a brain injury and multiple bone fractures.
