Why to open Xi'an to arrive the motor-car group train of Urumqi?

The motor-car of Urumqi still basically is slow, in those days the motor-car of the motor-car of Urumqi and Yunnan Guizhou moves with daystart, we know, the landform circumstance of southwest, hill is much, channel is much, flat one do not give 10 kilometers soon, can sail speed is every at the beginning of family motor-car small 250 kilometers, and sail at the beginning of the motor-car of Urumqi rate is hourly just 200 kilometers, road condition compares the landform of Xinjiang a lot of times southwest, eye shot good, drive to be able to see about a hundred kilometer, but can run only horary the speed of 200 kilometers, really wasteful. The road with respect to Xinjiang besides with eye shot, run hourly 400 kilometers are no problem. Say so, urumqi arrives Lanzhou it may not be a bad idea, to Xi'an it may not be a bad idea, want repletion increases speed per hour only. It is the Gao Tie that Urumqi also can open to leave to the haul distance such as Shanghai again, and can arrive directly, run by day Gao Tie's speed, run in the evening the speed of common express, passenger also need not stopover change, change a driver only all the way this is much better ah, answer to apply neatly, not so dogmatic. Right incorrect.
