I think rail service was discontinued to Benson AZ about 10 years ago. Try this toll free number for more information.

In order to answer this question one would need YOUR starting point. Since I live in Arizona the time would be in hours not days. I assume you do not live in Arizona since you ask how many days.

depends from where. From Phoenix, less than a day.
