After I was hired as a developer, I was given access to all the files, including the Blue Mars yaml files. I'm sorry to say I was not able to get the yaml files for BM pushed to Steam in the last few updates as we had to prioritize other things. For now, you can reference my BM mods for some hints at these hidden yamls.

Where did you get the info to make this mod? I can't seem to find it in either the modding pdf or the datamodels game folder

Works fine with 1.8

Hello, does it work with 1.8?

Noice. Came here looking for a mod like this. Would love to see a hyperloop-esque system instead of this (seems a tad unreasonable that seaborne vessels can travel as fast as land-based vehicles) but I truly appreciate you sharing this with us!
