The same feeling you get from seeing your piece roll into the station is the same feeling I get seeing my piece on a freight car get caught on the other side of the country, knowing people have seen it all along its journey, and will continue to see it for years.
Also, there arent extensive metro systems in the States. But there are vast amounts of freight lines and millions of freight cars.
This argument is apples and oranges. Both are good in their own right but are two different things.
