Lots of things in SA are much more overpowered then this mod

I'm still processing that foundries more then double amount of resources (and this is without modules!!!) you get from ore and here you say that bigger and faster trains are overpowered

From my (albeit minimal) testing, the trains would get extremely quick, moving a vast amount of resources. I suppose for longer play processing millions of resources every minute it could be considered balanced, but for casual play it's quite powerful, at least in my opinion.
