Yeah. We could get the NS heritage units, too (including the ES44ACs). Still hoping for an SD70ACe-T4 pack with UP (SD70AH-T4), EMD Prototype, and CSX (ST70AH) units.
sd70ace as rear dpu suffer broken dynamic breaking (after automatic brake trimming, rear dpu sd70 is losing dynamics - till automatic is to off - bailing off doesnt help). So I have mixed feelings about sd70ace in current state...
