alt Hacker NewsI haven't played the space expansion, but from old vanilla I only used trains for bringing ores to the main base. For rare low throughout recipies the flying bots (I forget the name for them) worked well, and towards the end of the game they got pretty fast as well.
As a longtime fan of trains in games like OpenTTD, it always felt like there wasn't enough of a focus on trains. Arguably this is something that Satisfactory did slightly better, there was more reason to use them there (that game certainly has other weaknesses though, and overall I prefer Factorio).
I'm am curious how you used satisfactory trains - I always found the satisfactory stations to be so overwhelmingly huge that they basically didn't fit anywhere (unless I build a layer of foundations a couple of hundred feet in the sky, which feels like cheating)
