AMTK 164, the Phase 4 heritage unit, is likely the most common heritage unit to run on the Zephyr (and over the Moffat). I think I've seen this one way more often than the Phase 1 through 3 heritage units. In any case, it is leading the Zephyr west around Big Ten Curve this morning, along with AMTK 23.
