I was lucky enough to get the old EMD Demo SD70ACe from VMD, but the payware models are replaced by the newer Jointed Rail ones since they're all made by norfolksouthern37. Don't worry about the VMD Geeps (if you're talking about the GP 7/9), because the Erecting Hall will have them back along with the F45/FP45 and SD45, but all as freeware. Just like I told someone else about the FP45, just please be patient and I'm trying to because since I came way too late on buying the original VMD SD45 and F45/FP45.
Once these models come back online fixed and even have new features (I even suggested a custom interior for the F/FP45 to replace the default F7 cab used in the original), I don't think these would look terribly out of place in newer Trainz versions (TANE & up) and all the old versions of the VMD website will still be used for your viewing pleasure. I'm just one of those people who somehow treat older content like they're old collectable toys despite not having collector's value and more easily mass produced since they're virtual, not physical.
