From a post by Milwaukee Alerman Robert Bauman on the Milwaukee Biz Blog:
Milwaukee County Clerk Joe Czarnezki has floated the idea of establishing a high-speed rail station in western Milwaukee County in the vicinity of the Milwaukee County Research Park. This is an excellent idea that deserves serious consideration by the state Department of Transportation and the Federal Railroad Administration (FRA).
In addition to the research park, this station would serve dense commercial development along Mayfair Road and the Milwaukee County Medical Complex. Employment in this area is second only to downtown Milwaukee. Moreover, this station would serve relatively dense suburban residential communities as well as west side Milwaukee neighborhoods.
A station on the high-speed rail line in the vicinity of Watertown Plank Road and Mayfair Road would be easily accessible via major arterial roads and within one mile of I-94 and Highway 45 interchanges and within one mile of busy Mayfair Mall. This station location would also be accessible to existing Milwaukee County Transit routes and could serve as an intermodal terminal for enhanced local transit service.
In short, this station location would generate significantly higher ridership than a stop in Brookfield.
