Text: Also, small railroads are exempt from the Tier 0 remanufacturing requirements for their existing fleets and the railroad inuse test program included in the rule only applies to Class I freight railroads, thus exempting all small railroads from the requirement.
Entailment: The requirement of Tier 0 remanufacturing is waived for all small railroads.
Contradiction: Small railroads have every stipulation that Class I freight railroads have, and a few they don't.
