Some trains may have the same function as buses or trams in other places (and metro… is metro a train here?), so the everyday commute of people in city A may not be that different than commute in city B, when first uses trams, and the second one has a local rail network with light trains. Actually the trains would probably have bigger negative impact on environment and life conditions in this scenario.

The environmental impact is gonna depend a lot on how the trains are powered. Some European countries are nearly 100% electric now. Others way less.
