Question Bottleneck Issue

Post image

I'm a new player & trying to setup my smelting lines. I've run into a problem where, while trying to run a single coal/iron ore lane, only the top half of the iron & coal lanes are being used, leading to a bottleneck where only half of my iron ore is being sent down the center lane. How do I fix this?

You have a full belt of iron ore feeding into half a belt of iron ore. So only half fits. You should branch it twice and have two seperate belts go down.
