This great looking consist just happens to be 75% EMD which, of course, is something of an oddity with GE dominating. That fact is unlikely to change anytime soon. It sounds like GE will have a Tier 4 compliant engine ready by mid-2015 whereas EMD says they won't even have a prototype until 2016 and won't be ready for production until 2017! All new engines must meet Tier 4 EPA emissions standards starting January 1, 2015.
