GE said it expects that the locomotive will meet the U.S. Environmental Protection Agency’s (EPA) Tier 4 emission standards. Interestingly, GE said it will meet Tier 4, “with technological advancements versus costly alternatives, which require special exhaust additives and infrastructure investments.” Read urea-based SCR.
