Description:
ES44AC Tier 4 Locomotive painted in Canadian National Livery. Thanks to Dave Snow for creation of this model and giving me permission to reskin and upload to the DLS.
In August 2012 GE released its Tier 4 ES44AC prototype, this locomotive looks very different from a Tier 2/3 ES44AC. GE is now in the process of building 20 more Tier 4 ES44AC's. Tier 4 regulations started on Jan 1st , 2015. This Tier is the final and most stringent of the standards.
Tier 4 ES44AC's retain most features of previous ES44AC's, but they have raised humps in the middle, as well as a larger, more sloped radiator in back with two cooling fans.
