Walker has a lot of irons in the fire, but the High Speed Rail they tried to put in from Milwaukee to Madison was full of holes and not one he wanted to keep in the fire. Talking to family who lived along the route, it would not have stopped at some places, unless the city or village PAID for the stop to be put in. Further biggest gripe from the non train supporters was the fact that the train did not intend to go into Madison, but rather to the airport which is on the fringe of the north side of the city. Then they were arguing in good ol Socialist Republic of Madison on whether busses will be used to get people from the airport to the downtown area and if that would cause more busses to be needed and increase a CNG footprint.
I support trains, but lets have some common sense. If it is to connect Milwaukee to Madison, then have it go where the people need it to go.

The MKE-MSN Hiawatha extension from a few years ago did indeed initially include a Madison station at the airport, rather than downtown - that was because MKE-MSN was the first phase, and further extensions to the Twin Cities would have used the line along the airport - so the airport was chosen for a legitimate reason (but certainly one that there were many arguments against). However, the MSN station was changed from the airport to downtown (near Monona Terrace) as the plans were refined and nearing (expected) construction. Intermediate stops were planned in Brookfield, Oconomowoc, and Watertown. As I recall, the communities were expected to assume ongoing maintenance of the stations, but the project would have constructed them (or at least constructed a basic station, that the community could choose to enhance if desired).
Let's be clear, though - Walker did not oppose the MKE-MSN extension because it was not well thought out - if that was truly the case, he could have worked to improve the plan.
