Well Ohlone Greenway is coincident with the BART tracks. BART still operates there, just above/below the walking path. The other example I gave replaced a railway that had been abandoned for a long time. I agree that rail needs a revitalization in the US, but at least here in Ohio, the problem is not right of way, but instead changing population patterns and competition from more convenient travel. I'd love to take Amtrak to Chicago for a weekend trip, but it costs as much as a plane flight and takes longer than driving a car or riding in a bus. Fix that problem using the existing right of way, then we can talk about building more. The coasts are a bit different.
