Just a few items: 1. The cost savings on road maintenance could be done much cheaper. According to the linked report (this is an older report - Robert or Bruce would you have a more updated report?), you would just have to remove 2-3 semis per week to negate the potential savings from people riding the trains. I'm sure that could be done for cheaper than $1 billion over the next 10 years. "Cost. One legal 80,000 pound GVW tractor-trailer truck does as much damage to road pavement as 9,600 cars."http://www.saferoads.org/issues/fs-trucks.htm 2. How will this ease any congestion in Milwaukee or Madison? People will still have to drive into Milwaukee to get to the station, and drive from the Madison airport into the city. Some traffic can be alleviated by shuttles, but that would primarily be at the destination side. 3. In regards to the 30% increase in popution, there will also be a great increase in technology. Many more people will be able to work from home, or alter their travel times to work by being able to do some things at home. There will also be increased technology as far as vehicle mileage efficiency, and road construction, to make them last longer.
