I’m a 18-year old boy from Sydney, Australia. Recently I had my first ride on a long-distance train. We got on in Sydney and we got off in Alice Springs, more than four thousands kilometers away. The food on the train was great. We eat great meals cooked by experts. For the first a few hundred kilometers of the journey, the scenery was colourful. After that, we saw abandoned farms which built over a century ago.
