We have the UP SD70ACe and NS ES44AC (except for the Conrail unit) Heritage Fleets in game, but we are missing some other heritage locos. Here are my ideas: 1.) CSX Heritage Fleet Pack: CSX just finished painting a bunch of their ES44AHs into heritage locos. They also have a B&O Heritage F40PH for their OCS Train. The CSX Heritage Fleet Pack should include all 20 of their ES44AH special locos (including the Conrail unit) and the B&O F40PH OCS unit (as well as the other F40s on the roster). Perhaps some new freight cars and the CSX OCS Train for Sand Patch Grade could also be included. The B&O, Chessie, and WM units would be perfect for pulling heavy freights on SPG. 2.) NS Heritage Fleet Part 2: SD70ACes, Conrail ES44AC, and TAG AC44C6M: We need the NS Heritage SD70ACes for Horseshoe Curve. This NS Heritage Pack should also include the Conrail ES44AC. Then NS just recently released a new Heritage Unit: AC44C6M #4851 in the Tennessee, Alabama, and Georgia (TAG) livery. Perhaps the TAG AC44C6M (along with other NS AC44C6M units, including the #4822 Honoring Railroaders unit and other special-liveried units too) could be added as a separate pack. 3.) BNSF ES44AC 25th Anniversary Units: While BNSF doesn't technically have a Heritage Fleet, they did repaint 10 of their ES44ACs with 25th Anniversary markings to honor the railroads that merged to form the modern BNSF: BN, GN, NP, SP&S, ATSF, C&S, and SL-SF (Frisco). That counts, doesn't it? These ES44ACs would be great to see on Cajon Pass in heavy freight services. 4.) Canadian National (CN) ET44ACs and SD70M-2 Heritage Units: CN has a small Heritage Fleet with 4 ET44ACs (IC, EJ&E, WC, and BC) and an SD70M-2 in GTW livery. We have the SD70ACe in game, but the CN SD70M-2 would need DC traction motors. The ET44s could also be added in CN, CPKC, KCS, UP, NS, CSX, and BNSF (both ET44C4 and ET44ACH versions) liveries.
The Conrail unit would of came with the other pack, but there is no licensing deal with the CSAO, so it was removed. Skyhook does have it done, but they cant included it till licensing is solved....
If we are talking real heritage, then I would love to see a well modelled late build Alco - C420 etc. in the game.
