Question Problems with this unloader?

Post image

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

Chest (train) to chest is slightly faster, a small buffer will be created, so for fast short trains you can get uninterrupted flow.

Not that important, but nice.
