The inserter directly behind a junction merge does not unload from a cargo wagon.
If you remove the inserter and place it again it works one time, then when the next train rolls in
it stops again.
It won't insert into the cargo wagon either:

Does it pull from a train that is sitting on the curve? It might be that the inserter is checking the curve instead of the straight.

can you provide the save?

So i can take a look at it

Yeah, it is most probably sleeping on the other rail segment. We'll think what can be done about that without inducing too big performance loss just due to supporting that special case.

I remember fixing it some time ago. The inserter should always select the straight rail in this situation, not the curved one. Are you sure the train is on the straight rail?

It seems to only happen when the train comes from the curved merged rail.

I'll extend rail wakeup logics to scan all adjacent rails as well when train stops, so whatever rail inserter chooses for sleeping - it will not be zombified.
EDIT: and actually one of inserters in this save is sleeping on curved rail I guess it has decided to do so when straight rail was not yet built.

Fixed for coming release.

Thank you!
