As Todd noted, Hayward station is unmanned. The closest manned stations are Jack London Square in Oakland, or San Jose. You could buy a ticket there, on your smartphone, or on a computer at the Amtrak web site and print it out. Some other stations like Santa Clara Great America have ticket machines, but those are for travel to or from those stations.
No. Hayward is unmanned. But you CAN buy tickets anywhere on your phone using the amtrak app or web page
