    Trains don’t leave exhaust in the upper parts of the atmosphere, though, and depending on how the electricity was created, it could be neither did its energy source—though I suppose there’s no avoiding that manufacturing any kind of plant and the train itself did cause emissions.

      @flux @QuinceDaPence Concrete and steel (for stations, track, etc) matter. So does the electricity used to maintain stations, not just propel the train. So lifecycle emissions of a train are immensely complicated, plus then you get into how to route a new rail line without destroying too many ecosystems.

      Even so, clean electricity is the easy bit compared to making planes clean. More trains please.
