Caption: In 1993, Burlington Northern had placed a record setting 350-unit order with GMDD in London, Ontario for 4,000 horsepower SD70MAC’s totalling $675 million. In December 1993, the first one, BN 9400 rolled-off the assembly line at the London plant with 349 more to follow over the course of the next couple years. Painted in the BN “Executive Scheme” the units departed London for delivery to BN in Chicago via both CN and Canadian Pacific. Here BN 9429 and 9430 are viewed at CN’s yard in London waiting to be lifted after having made the short trip from the GMDD plant.
