The SD70MAC is seen on almost every class 1 railroad but it would be cool to see a CSX SD70MAC that once you buy you would be able to drive it on Boston Worcester or Sand patch grade it would also give a little more love to CSX routes because we haven't gotten a new American freight diesel in a while .
The CSX SD70MACs have been rebuilt as SD70ACs with upgraded electrical systems from Mitsubishi. CSX also has a couple of Operation Lifesaver units that should be included in a CSX SD70AC DLC Pack. I'd prefer a BNSF SD70MAC/SD70MACe DLC Pack for Cajon Pass that could also include BN and BN/BNSF Patched SD70MACs along with the "Vomit Bonnet"-liveried unit. The Alaska RR also uses SD70MACs in both freight and passenger services, so those could be included in an ARR Anchorage-Seward TSW Route. KCS/CPKC also rosters SD70MACs. NS has rebuilt SD70ACCs which are basically former SD70 Spartan Cabs with new electrical systems, upgraded prime movers, and new wide cabs similar to the SD70ACes.
