One thing to mind is that infrastructure project's financing and cost allocation is different in Europe vs North America. All countries and jurisdictions counts things differently. Are stations part of the cost, what about roads and paths leading to them, getting right of way, buying land etc. some of these costs are often incurred by local governments and municipalities and aren't considered part of the infrastructure project while other projects will include them as part of their costs. The Milan project is fantastic, but it's difficult to have more than a ballpark comparison based on general numbers such as these.
