The old rail route through the Gotthardt pass runs in a set of vertical spirals to achieve the vertical elevation.

This megalink shows, I hope, a Google Maps 3D rendering of the pass and the rail route:

Note that the big loops are inside the mountain.

We have some absurdly long (3-4.2km) freight trains in Canada, and they go through systems like this all the time. You can see the front of the train at the top of the mountain while the bottom is still going in!
