It's not easy, but has been the 'best experience of my life' Palden Nyima

Working on the Qinghai-Tibet Railway is really not easy, considering the lack of oxygen in the high-altitude environment. But I regard working on this railroad as the best experience in my life.

I am always struck with the beautiful landscape - the snow-capped mountains, the vast Changthang grassland and the wildlife, including yaks and Tibetan antelopes along the line.

I have been working as a railway policeman for 29 years, and I have been in the Qinghai-Tibet section for 10 years.
