We have some pretty cool modern US diesels in TSW4. I'd like to suggest a few that I think we need: the EMD SD70M, SD75M/SD75I, and SD70MAC. EMD developed the SD70Ms in the early 1990s based on their SD60Ms. The cabs of the newer units were isolated from the frame, which made the cab interior more quiet and comfortable for engineers. The units produced 4000HP with an EMD 710 Prime Mover. EMD produced the AC Traction SD70MAC based on their prototype SD60MACs that were operated in coal-hauling services on the Burlington Northern RR's Powder River Basin in Wyoming. The SD70MACs were proven successful in heavy haul freight services. Also, EMD's new steerable Radial Trucks (GE would make their own version, too) were a huge plus, despite the higher maintenance costs. BNSF, KCS, and CSX have started rebuilding their SD70MACs as SD70MACes with new electronics and control systems. The SD75Ms/SD75Is operated by ATSF/BNSF, CN and ON were basically uprated SD70Ms with 4300HP. Here is my list of the three loco DLCs and what I think should be included (obviously for existing routes): -EMD SD70M Pack: -UP SD70M (both standard and flared-radiator versions) for Cane Creek and Sherman Hill -NS SD70M for HSC -SP SD70M for Sherman Hill and Cane Creek -CN SD70I (Isolated Cab Version of the SD70M) for CN Oakville Sub -EMD SD70MAC Pack: -BN SD70MAC for Cajon Pass -BNSF SD70MAC(e) (executive livery, "Vomit Bonnet", H2, and H3 Swoosh liveries) for Cajon Pass -CSX SD70MAC/SD70AC Rebuild for Sand Patch Grade -NS Rebuilt SD70ACC (updated SD70 Spartan Cabs with SD70ACe noses and SD70MAC cabs) for HSC; include special painted locos -EMD SD75M/SD75I Pack: -CN SD75I/SD75ACC rebuild for Oakville Sub -ATSF/BNSF SD75M (Warbonnet and H3 liveries) for Cajon Pass -BNSF SD75I (Warbonnet and H3 liveries) for Cajon Pass -Rolling Stock to include: -Coal Gondolas/Hoppers -Steel Coil Cars -New Intermodal Well Cars -Cement Hoppers -NS Roadrailers
