Gas leaks with many fires in Lawrence, North Andover area. MBTA trains and Downeasters are being held until further notice. 6PM 9/13.
Several street gas mains in Andover, North Andover, and Lawrence became overpressurized probably due to a malfunctioning gas substation pressure regulator. This caused damage to water heaters and other equipment in scattered homes and buildings throughout that area and some of the homes and buildings (reportedly about one hundred altogether) caught fire or exploded due to gas leakage from the damaged equipment.
Possible exterior damage to gas mains or equipment from the overpressure leading to an accumulation of gas in the atmosphere outside that, if near the railroad, could be ignited by a passing train.
