I really enjoy your mod, I've been looking for a decent one that adds nuclear trains and this one is it, so great job! I was looking for more of a mid-late game option though, rather than a super late game behemoth, so I uploaded a rebalanced version of this mod that adjusts the tech cost, speed, and fuel consumption to be more in line with the start of purple science. If you ever add configuration options to your mod or multiple tiers of nuclear trains, let me know and I will remove my revised version.
