Help - do I restart?

First playthrough, I have about 50 hours sunk into this run and I am having resource troubles and just generally the ability to expand my base. I have never seen the end game yet but I physically cannot collect enough iron and copper to feed my factory and I suck at planning the trains. Just feels generally crammed and I didnt plan properly. Should I restart and just plan for 10 lanes of resources each to come through the middle of the factory?
