 "Between Austria and Italy, there is a section of
  the Alps called the Semmering. It is an impossibly steep, very high
  part of the mountains. They built a train track over these Alps to
  connect Vienna and Venice. They built these tracks even before
  there was a train in existence that could make the trip. They built
  it because they knew some day, the train would come."
