Work has started on a new high-speed rail line between Chengdu and Lanzhou. When completed in 2014/2015 it will cut travel time between the Sichuan and Gansu provincial capitals from 20 hours to four.
As well as being a shovel-ready infrastructure project to set free stimulus yuan–the line will cost 62 billion yuan ($9 billion), state media reports– the line is part of a grand plan to open up transport links to western China (and beyond), shipping Xinjiang’s oil, coal and cotton east and tourists in the opposite direction; the route will pass through the Minshan Mountains, home to giant pandas, and Jiuzhaigou and Gannan, both popular destinations.

China's Rail Network
Work is expected to start later this year on other new rail lines connecting to the Chengdu-Lanzhou railway, including Lanzhou-Chongqing, Baoji-Chengdu, Sichuan-Qinghai and Sichuan-Tibet. These complement the high-speed inter-city lines being built in the east.
Overall, China has earmarked 2 trillion yuan ($300 billion) of spending up to 2020 to improve its rail system, particularly for freight, expanding the network from 78,000 kms of track to 120,000 kms.
