Choo-choo! ... Officials broke ground on a new high-speed rail system that will connect Southern California and Las Vegas. The Brightline West system will reach speeds of 200 miles per hour across a 218-mile route between Las Vegas and three stops in California, which is about as fast as other high-speed systems around the world. Brightline West hopes to be operating by 2028, when Los Angeles hosts the Summer Olympics. And if they get this thing going, it will be the most advanced high-speed rail system on U.S. soil.
