This 50’ Standard Box Car is painted blue with white lettering. Originally built in 1948, Canadian National acquired these cars from GTW in 1974. CN painted cars from this series in either blue or brown. None of the blue cars in this ex-GTW series displayed the ‘CN’ logo. The U-1 symbol with the yellow (safe) dot indicates the car is not equipped with U-I type wheels, suspected of catastrophic failures while in service. U-1 inspection symbols were applied in 1978. By April 1988, all cars from this series had been removed from CN’s roster.
