The total cost of the Lanxin Express is as high as 143.5 billion yuan (US$20 billion), and each suspension may cause losses of hundreds of millions of yuan.
The Lanxin line connects Lanzhou (4.4 million people) with Urumqi (4 million people). The Express line is currently used mostly to relieve freight traffic on the parallel conventional-speed line.
IIRC it was thought to be better to build a high-speed alignment than to build another low-speed one because of the costs inherent in laying 1776km of track in some of the least hospitable conditions on the planet. The marginal cost of building a high-speed line wasn’t that much greater than the cost of building another line in the first place.
