Spiral Tunnels and a Very Rocky Mountain.

There are two spiral tunnels on this section of the mountains. Unless the train stops it is hard to grab a picture of both entrance and exit. The height difference is about 50 feet and 56 feet (15 and 17 metres). They did not seem to be aware that we also have spiral tunnels in New Zealand built for the same reason - to reduce the gradient to more acceptable levels.
