At 12:10 a.m. on December 28, 1966, eastbound first-class passenger train No. 563 consisting of a single car diesel-powered passenger unit operated by the Boston and Maine Corporation, collided with a northbound motor tank truck owned and operated by the Oxbow Transport Corporation of Lexington, Massachusetts, stopped across the Second Street railroad-highway grade crossing at Everett, Massachusetts. The collision resulted in the death of 11 of a total of 28 passengers and 2 of the 3 train crew members, and other injuries and damage to property. The semitrailer of the tank truck containing 8,300 gallons of fuel oil ruptured on impact covering the forward end of the single railroad passenger car with the flammable oil. Low-order explosions and a rapid spread of flames immediately covered the forward section of the car. The fatalities were due to thermal burns and smoke inhalation, rather than from collision injuries. The truck driver had left the vehicle prior to the collision and was not injured.
