Steinio, thats what I did, so it asked for 6 full trains to deliver without the seventh filled up half
But I think the limit to the train numbers will have the same effect for me, I'm testing that now, just updated.

I really like this mod, it has become one of my standard mods pretty fast. But I came across a jamming too. I've build a train system in a beginning factory, big enough for some major growing without the need to create more trains along the way, resulting in 40 trains inactively waiting ( intended )...
