One of the few good things to come out of the next four years is that California will be able to basically ignore any federal requirements that serve no real purpose.

The requirement is a bit garbage. Most other countries manage to run their rail networks effectively without having their trains blast the horn at every crossing. When they do, it's typically two short tones, not the way the US does it.

I mean, sure. But this very article is about having built (erected?) electricity poles for those trains to run on.

Reno put their downtown train track underground. It’s a short segment but it’s doable.

Emeryville has no horn train crossings. It’s doable.
