Description:
ES44AC Tier 4 Locomotive painted P&O. 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.
