This news item broke before Christmas in Milwaukee. I think it is dreamland but thought I would share with the community here as it sounds like a copy of Brightline with some twists…

Waukesha County last saw Milwaukee to Watertown rail commuter service provided by the Milwaukee Road that lasted a full year after Amtrak was formed (April or May of 1972). Basically, the service was one train in the morning towards Milwaukee and one train out at night towards Watertown with the train over nighting in Watertown. The train was made up of an F unit and two to three coaches in the UP yellow and gray paint. Milwaukee Road suspended the train shortly after a derailment in Brookfield, WI caused by a truck striking the North Avenue overpass trestle at the time and knocking the track out of alignment. Milwaukee Road was angling for a subsidy for the train from Milwaukee County but decided after the derailment that enough was enough and cancelled the train.
