omfg, thank you

here is a snip of the front wagon, the top side chest have copper in them and the wagon is nearly empty, the few items in the chest where from when i fed the bottom insterters with copper

the connected ones are not in question as there is only wires to inserter columns 1 and 3 respective to the train 1 being the front 4 being the back, columns 2 and 4 while some inserters work the ones one top side dont, there is space in the wagon.

Hi,
I have an issue with inserters inputting to a wagon, that has either nothing or some items, see snip and save file.
The loading mechanism is split just to prioritise filling of the back cargo before the front and is not in question.
the inserters just hang without adding to the wagon, even ...
