A new Tier 4 locomotive leads a heavily powered high priority train westbound through Medill, Missouri. This was the site of two recent derailments and is only now looking back to normal. The ground is still littered with protein drinks and hair products from the destroyed containers that were scattered around the area.
Tier IV locomotives are the safest, cleanest, and most fuel efficient locomotives on the rails today. Unfortunately, most of them are ugly and are as quiet as an ACS-64.
