[h]3 line belt[/h]

[b][i]Belts with 3 lines instead of 2![/i][/b]

[b]Why?[/b]
belts of 3 lines create a totally different logistics, thus expanding the possibilities of the user.

[b]how?[/b]
It is only possible to insert items in the lateral lines if we merged a belt in the respective side and it is only possible to put in the center through inserters.
However the belts' speed is reduced to 66%.
when an belt merge with an underground belt sideways, only the farest line will continue.

I think you can forget that idea. The 2-lane belt system is maybe the oldest mechanism in the game, and has been polished and optimized a lot. I'd be baffled if the devs threw everything to implement 3-lane belts.
BTW : A few years ago, it was possible to exploit a glitch to create a 3-lane belt, but the mechanism that used to be exploited has changed, and it's not possible anymore.
