[GS] Global Warming is too powerful

[Tech Osen]

In my 3 games so far I found railroads to be a massive contributor of CO2.... in one game I connected all 10 of my cities with rail and despite not having a single factory, I was the 2nd largest polluter globally! (also had scant modern military units)

There should be a city project to electrify the railroads in that city where it stops giving polution but needs another power point.

But as i understand railroads don't have ongoing polution as powerplants or units. They pollute only on the amount of coal that you spend to build them. So what's the point of electrifying them? Units on the other side is a problem.
