ArcelorMittal 150 has a new paint scheme to go with its latest merger. In under 10 years, this caterpillar-powered oddity has gone from grimy White to grimy Baby Blue to, now, soon-to-be-grimy Highway Cone Orange. All this time, it continues to be a fun operation to watch, as it shoves these iron slabs, hot enough to warm me up on the Ped Bridge, around a curve on its way deep into the plant.
