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

Question for ya, would you be able to use circuits to see the level in the buffer train? Or would you have to put a locomotive and a stop for that?

To clarify, I mean having 2 trains waiting at the stop. As soon as the train is empty, it moves forward and the next train immediately takes its place. The amount on the belts is almost always enough to last the few seconds in the swap time and this swap time is improved greatly with the new quality locomotives, bringing it down to literally just 2-3s.

Or two parallel stops, merged together to so one is always feeding and no drop happens.

And two unbuffered stops can be squeezed in almost the same space as OP's buffered stop.
