I have yet to actually beat the game, but this playthrough I decided on going with a central logistics hub and modular factories. All goods flow into and out of the hub. Blueprints for rail bridges have been essential, but modularizing the factories has really helped cut down on the complexity. Most primary manufacturing is done on site at the point of resources, and further manufacturing is being done near the hub. If I can take advantage of a resource while making higher tier goods, I will. I also have made sure to integrate a hypertube network into the rail bridges, which has really helped with getting around. I’ll sometimes add “booster” sections in the runs to speed things up.
How did you get a proper straight railway blueprint that is exactly the length of foundations or whatever base you used? Mine either hung off the ledge or was too short so I ended up making my network manually, and making railways on the fly just made everything curvy.
I placed the bridges without rails and laid the track afterwards. You can also hold CTRL to place straight rails. I also find that it helps to place a short straight section on either end of a curve to force it to stay straight after the turns. Granted, now, you can just scroll to adjust your placement. Now that 1.1 has landed, it’s so much easier to position rails and blueprints.
