    UP always likes to keep you on your toes. Both of those units happen to be Tier 4 units with the 4 Cycle 1010 engine...however, the Tier 4 credit engines they've sold to UP this year (by law, EMD and GE can sell a tier3 unit for every Tier 4 unit they sell. They are called credit units.) are also called SD70AH.
