Amtrak's Saturday evening Hiawatha service will continue until further notice. "The Saturday late evening trains have shown higher ridership during a trial period than the early morning trains they replaced." This is a positive development. We don't refer to Milwaukee as the Beer City for nothing.
There might be other days of the week, starting with Friday, for which a late evening train proves useful. Perhaps the day will come when the Chicago Wolves hockey team refer to their series with the Milwaukee Admirals as the Amtrak series for reasons other than naming rights.
