I sort of wonder if private train companies in the US would achieve the sort of interconnection we have in Tokyo. The train station nearest to my house is owned by one company, but after going East two stops the stations and rails are all owned by another company. The station that's part of both of these companies' lines is also a major transfer station to a major line owned by a third company. As a user of transit I mostly don't have to care about this, but I ended up calling three companies when I lost something on the way home.
