It’s a tunnel with electric trains. I volunteer my pasty white ass’s house as tribute for this. My city has near zero rail service and I’ll take it in a heartbeat.
Yes, the US has been using infrastructure to harm minority communities for generations, but so far this doesn’t seem to be the most egregious example of that. The exhaust system being next to a school is the only concern, but only if there’s a fire in the tunnel (which should be rare unless Boeing starts making trains).
Either move the exhaust or move the school while you start digging that new higher speed tunnel! Let’s go for some real modern transit!
