Identity Crisis
Two NS units, an SD70IAC and an AC44C6M, are throttling up out of an approximately 45 minute long stop in Chesterton, Indiana.
The lead unit on 27G is quite interesting, on the outside, the engine is designated as an SD70ACe. However, the builders plate on the inside has the designation as SD70IAC (IAC stands for Individual Axle Control). These units also have 200 more horsepower and can meet Tier 3 emissions standards, unlike the 1000-1174 numbered SD70ACe's, which have 4,300 horsepower and can only meet Tier 2 emissions.
