I got this DLC on sale but I'm disappointed nonetheless. - tracks are awful to place since terrain must be perfectly flat from start to finish. - most train features simply don't work. In the end, it's usable ONLY to move workers from a dome to far away workplaces. - buggy. You have to search the internet for workarounds on how to delete a trainline. - design is lazy as well. The train model is no more than an ugly tin can. It appears empty regardless of its load. It teleports on tracks to turn around, screw animations. Totaly unworthy of the base game's quality.
