As far as I know, you can leave your vehicle for an extended amount of time(ie.10days). Amtrak has a small parking lot in front of the station that connects to the Bakersfield Library. Keep the vehicle in the Amtrak area & I would double check with Amtrak Staff inside to make sure there is some security personnel. The area is not the worst part of Bako, it's not to far(walking distance 5 minutes) from the main Headquarters of the PD, but check to make sure there's not been any car "break-ins" recently. Bako is a city with more than a quarter million people, so be cautious. But, genuinely it's an area that is safe typically.
You can try.
