In
both cases the correct time zone is not being received from the Amtrak app, so they appear to be somewhat related.
I don't know what quirks Google Calendar has, but it books the trip in the time zone of your phone, which is how you'd expect it to behave if it doesn't otherwise get any time zone information.
