I'm a Amtrak bus driver, it can be busy at times, but seems to be safe, waiting inside mote comfortable, and safer.
It's pretty safe there at the station. Lots of people get off at Fresno. There is taxi's, Uber and lift if you use your phone. Unless someone is picking you up. There is a turn about where your ride can pick you up also. The station is open if you don't feel to comfortable you can wait inside.
