The two commuter rail corridors proposed by the Preliminary Plan would connect Kenosha, Racine, Milwaukee, Wauwatosa, Brookfield, Oconomowoc, and communities in between by making upgrades to existing freight rail corridors to allow passenger rail atspeeds of up to 79 miles per hour, providing a fast service connectingmany of the larger population centers in the Region with vehicles similar to those shown here. In addition to the two corridors included in the Preliminary Plan, there are a number of other freight rail corridors in the Region that could be utilized for commuter rail, should an entity be interested in pursuing their development. These additional corridors are not included in the Preliminary Plan because they are forecast to have markedly lower ridership than the two corridors included in the Preliminary Plan.
