The Yolo Shortline is a working freight railway.  Unlike tourist railroads that make money from offering passenger service, the Yolo makes most of it's money hauling freight in California's Central Valley, interchanging with the Union Pacific in Sacramento.  Passenger service is just a way to make a little more money on the weekends.

Shortly after we arrive, a Yolo pickup truck arrives, and the crew turns the small wooden structure into the ticket office.
