Factorio Forums

Hello,
I finally got into trains and rails in Factorio, but I think I am doing something wrong.
Basically, when I try to build a track in cirlcle-like shape it usually ends like this: http://puu.sh/3y4WH.jpg
Sure, the trains can go on those just fine, but isn't there a better way to do this?
In http://www.youtube.com/watch?v=Vmp66SmUztQ I can see fine, round pieces of track.
What am I doing wrong? Or is it just me thinking that the rails in video are actually rounder?

This is an optical Illusion. Zoom in and you'll see, that the rails are round...

:l
I feel like an idiot now.

Well, I guess this is intended, and they might be round, but they aren't circular, no matter how you build them: https://wrtlprnft.net/factorio_circle.png

Edit: I do like how you can build really chaotic intersections: https://wrtlprnft.net/factorio_chaos.png

It isn't round, cause there is a pice of straight track between the 45 degrees curves, but I meant the optical illusion of convex instead of concave when you look at them. It's either concave nor convex it's straight.

A little bit like this http://ccl.northwestern.edu/netlogo/mod ... usions.png

I think the following image kind of explains what's going on:



As you can see, the rails in the curved rail segments are pretty perfect circles, but they aren't concentric. This means that diagonal straight rail segments are a tiny bit narrower than horizontal/vertical segments.

The transition between a curved segment and a straight diagonal segment contains a very tiny corner on both rails, but that's hardly noticeable.
