Never lose your childish enthusiasm

Between Austria and Italy there is a section of the Alps called the Semmering. It is an impossibly steep, very high part of 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 the train would come. A train track through the Alps before there was a train.
