We built our “impossible” railway with environment cared which is truly an extraordinary “Sky Railway”. How to protect the delicate ecosystem was among the top concerns. 1. What other challenges were met and overcome by the railway workers? Post-reading They have to apply state-of-the-art techniques（最新技术） to protect the permafrost（永冻层） in the subgrade（路基） of the railway embankment（路堤）; Around 550km of the railway had to pass through the places with permafrost, the Chinese successfully figured out ways to solve the problem, and ensure roadbed stability in permafrost regions by gravelling embankments(铺砾石堤) and vent-pipe(排气管) roadbed techniques. All waste water from construction and camp sites was processed to meet the corresponding sewage（污水） treatment standard before discharge. Solid waste from construction sites and trash from the campsites was sorted out and recycled whenever possible. Waste that could not be degraded（降解） was moved to appropriate places for batch treatment（分批处理）.  2. They need to make regulations to ensure the environmental disposal of the construction waste; 3.
