Flood in Piscataquis County, Maine

The second heavy rain event in 4 days led to flooding which contributed to a train derailment. The first heavy rain event from the 14th into the 15th produced general 2.50 to 4.50 inch rain totals. This left the ground saturated and water levels elevated. A second heavy rain event from the 18th into the 19th produced an additional 2.00 to 3.00 inches of rain. Flooding developed during the early morning hours of the 19th. The flooding overwhelmed a culvert located beneath a rail bed. Failure of the culvert led to a washout and collapse of the rail bed leaving the tracks unsupported. The unsupported tracks contributed to a train derailment during the early morning hours of the 19th. The first seven cars of a train derailed while crossing the unsupported tracks. No injuries occurred. The time of the initial washout is estimated.
