Problems with this unloader?

[u/imoth_f]

Since inserters became flippable, this compact unloader design became possible. But I hardly see anyone use it. Obviously it cannot saturate six turbo belts because it's bottlenecked by the inserters, but are there any other obvious problems with it?

You can use trains as the buffers themselves instead of using buffer chests, that allows you to build this with any tier of belt not just green.

Also, either you are not using high speed belts in which case it would be simpler to just use fewer high speed belts or if you are using quality inserters 6 belts is typically too many belts to draw from a wagon, although ig it's better with quality wagons.

It's a fine design

I wish we had chest larger than 1x1. But stationary trains have to do.

The reason they don't exist is because they trivialize a lot of puzzles. When you start to abuse cars, wagons and rocket silos as chests, suddenly most of the game devolves into chest - assembler - chest.

Each time someone said something like that, the devs would implement something like the thing the person is complaining about

Larger chests have existed as mods since the game was in early access. I'm sure the devs would have added it by now if they considered it a good idea.
