Lol, I have answered your question, just not to your pedantic standards. There is no study that encompasses every rail network in the world, just as there is no study that encompasses every combustion engine in the world. As the world isn’t working as a single entity to fight climate change.
I have given plenty of evidence to support my argument, you have only supplied two articles that did not support your argument, and we’re about the same train system.
You aren’t arguing in good faith, you’re just employing one logical fallacy after another because that’s all you have to rely on.
Expecting me to answer them first seems dishonest to me…
You made the original claim that there wasn’t a better answer than battery powered vehicles, so the burden of evidence is in your court. An affirmation made without evidence can be dismissed without evidence, but I was actually trying to educate you over a very important topic.
I guess that’s my fault for assuming that someone as terminally online as yourself could put their ego aside for meaningful discourse.
