Train travel isn't as common as it used to be, but there's one Amtrak route that train enthusiasts love because it's so beautiful -- the California Zephyr. The route starts in Emeryville, runs through the California delta, stops in Sacramento and then heads and over the Sierra Nevada mountains, eventually terminating in Chicago. This ride is on a lot of people's bucket list for good reason. But the California railroads also played an important role in the food history of the state and in the Civil Rights Movement.
