Getting back to the main point, I have some questions:
1) What exactly does DRM do for N3V ?
2) What advantage does DRM do for N3V ?
3) Why does N3V choose to use DRM in the first place (there must be some specific reasons) ?
4) Does DRM allow N3V to disable your DLC, if they find one abusing it's content, (file sharing, redistribution) ?
5) If only N3V went out of business, and only the N3V servers were "no more in existance", would DRM effect Trainz, and DLC assets ?
6) Is DRM used primarily to keep "Warez" users out of the Game ?
