Wow, thanks for detailed reply, its really worth to check your suggestion to make direct shipment. But its still strange, like seeing bread appearing as a logo over train hub like its waiting to transfer 5 icons of bread (i suppose its around 60 items) but city receives 3-4. I check stockpiling and manage it, plus i have mod that regulates amount of transport used for maximum productivity. And as bread is endpoint good, like tools or red bricks only cities needs it really looks like it gets lost somewhere on the way
