18x Copper Smelting Train-Feed

Need 3 seawater pumps & 1 brine dump to operate.
864 copper plates at full capacity (some scrap needed).

Workers count: ~660
Provide some graphite & water to boot up.

Use tips:
Train fuel type is H₂ by default, and can be changed with little re-piping. Compatible with electrified rails.
Trains are set to non-stop at station, so that different input types won't interfere with each other.
After booting up, the electric boiler can be replaced by a H₂ boiler.
Attach the add-on module to convert output to Electronics1.
