It's also worth noting that ICE train does not mean internal combustion engine train, which was my second read (my first read being some super-deportation-train probably doesn't need to be clarified as even as I imagined that I knew it couldn't be right). It means "Intercity train", which a quick lookup clarifies as an express train between two cities that's longer than a commuter train but with fewer stops than your typical regional train. Makes sense I'm not familiar with the term, as the closest match in my area is Caltrain (express trains, at least), which is still probably just commuter rail. I guess it's what CAHSR is trying to be.
