Who has lost an election because of a long distance train? Maybe someone who rail fans opposed lost an election, but is there the slightest bit of data that shows a causative link? Can you even point to a causative link between a local, a mass transportation/mass voter issue particularly involving a train that cost an elected official his/her job? The only one I can think of that even tangentially involved trains was Christy shutting down that bridge, and it was a mighty slim connection at that.
That's not going to change, at least not in regards long distance trains. Anderson is right to position a few as "experiential", and make them the rail equivalent of the Queen Mary 2 – a cruise ship that does a 21st century imitation of a passenger liner. The rest need to be reconfigured to move people – lots of people – to places they need to go every day. There's no secret about how to do that -- look at Europe, Britain, China or Japan.
Rail is too valuable to waste on amusement park service.
