I was wrong; executing cncnet5 don't revert changes.
If you need/want I can upload here several files, all the .bins that can be changed depending of the mod applied. I have several folders for every-mod, plus one to revert to the original state so the game will become stable again.
For you or anyone that need. All the files goes on the same folder, so recovering the original game it's easy :P.
I'm pretty sure the GG1 had the same stats in real life for it's entire 50 year service life. But they still seem kinda exaggerated, I'll admit.
And while we're talking about overpowered locomotives, let's talk about the FP45... I can't really remember right now, but the real-world FP45 didn't seem overly impressive.
Could I also submit some changes for your EXE? Mainly, I plan to boost the reliability of the SD45 and possibly the SDP40 to good or above. (The SD45 being a expy of sorts for the SD40-2.) I also would like having the SD45 available in the end-game as a mid-powered locomotive for lines with lighter traffic, and to reflect the SD40-2s longevity.
I will try that tactic with electric-freight and diesel-passenger when I can sit down for a while.
Edit - I'll think I'll hold off on those locomotive mods until I can remember how to use a hex editor...help?
The game probably makes track electrification too cheap (for both the upgrade and for maintenance), hence the easy rush from steam to electric. In reality, electric is probably only economically viable in dense urban clusters like in Western Europe, central Japan and America's NE corridor. The game also makes the GG-1 too powerful, taking the best stats from the end of its run, inflating those, and offering them starting in 1935. The 1935 version wasn't nearly as powerful or reliable.
Something like that also happened with the F9 diesel. I have no idea why it got the power and speed the game gave it (my mod pegs it back to what I've read about it).
However, the GG-1 is not available on all maps. In fact, electrics need not be available on all maps.
Something to try tactically: Haul your passengers with diesels, and haul freight with electrics. Then be careful about which tracks and stations receive electricity. This could segregate your fast versus slow trains (keep the slow freight off of your express lines).
Sorry about that XD I guess I should do a final release at some point. When the second campaign is done. Then, only then... then it will be perfect. All the fine-tuning, all the testing, will be done. Someday...
