2space rails or 3space?

[探求者]

Just started a new playthrough recently and I was designing new rails. I made 4lane rails with 2 rail tile spacing and I noticed my old rails have 3 rail tile spacing. So the question is, which is better?
3tile rails:
||xxx||xxx||xxx||
2tile rails:
||xx||xx||xx||
where x is a tile you could put rail on

Depends on what "better" means to you in this situation.

One can be easier to make transfer lanes. One uses less total footprint, one has more room for things such as lasers or stations or solar panels.
Depending how you are designing/using your intersections, one could be better.

In my opinion, i would go with the system that uses more space, because i like to make my bases bigger and bigger, so the extra space would reserve the ability to grow.

However i have found that properly thought out intersections provide much more benefit than simply more lanes.

Obviously 10 rail spacing is best ||xxxxxxxxxx|| because it allows you to do U-turns anywhere you want.
You can also fit a lot of solar panels so it's not like the space is wasted.
