IT has brought tremendous changes to people's lives across the chenghai sheet. Sung patel, sitting on the roof of the world, this one thousand nine hundred fifty six kilometer long railway marked its twenty of anniversary this july. Travel between the chenghai sheet, sung platter and other parts of china was once extremely chAllenging. Back in the nineteen fifties, camels were used to transport goods from shanghai to lsa shez zon, a journey that would take three to four months. Today, trains can cover the same distance in just forty eight hours. The railway has greatly boosted local business. A market for catapult or fungus has sprung up near shankar有way station。In the old days, traders had to drive for days to shez on to collect the precious serve. Nowadays, local people in sheds on can ship the urbs by train, and goods from this market can arrive in most parts of china within one day. Great changes have also taken place at loss of west station. The site used to be open wasteland with dirt roads. IT has now developed into a modern transport center with eleven routes transporting cars, home appliances, vegetables, fruits and various other goods. Local produce such as apples from ninety and shanon is also exported to nepal via rail to preserve the local ecosystem. Large sections of the railway are built on bridges, allowing wild animals to pass safely underneath. The population of tibetan antelopes in shez on has risen from around seventy thousand in the nineteen nineteen eighties to over three hundred thousand. Now we can frequently spot them running along side the railway. Furthermore, progress never stops. Earlier this year, china launched a new power supply project for the railway. Upon its completion, more trains will run on electricity rather than diesel fuel. Time flies. The sky railway keeps advancing IT not only shortens geographical distances, but also Carries bright hopes for a promising future for sheet on.
