My comment:
(a) The first two thirds of this article talks about things we already know.
Please read from paragraph 3 of web page 2 that starts with "Word went
forth."
(b) The report cites
Stephen Chen, 'Judgment Day' Fears for High-Speed Rail Tracks. South China
Morning Post, Jan 10, 2011

/article/Judgment-day-fears-for-high-speed-rail-tracks
("mainland could produce enough high-quality fly ash for the construction of
100 kilometres of high-speed railway tracks a year. But more than 1,500
kilometres of track have been laid annually for the past five years")
Note:
(i) fly ash 粉煤灰/飛灰
http://en.wikipedia.org/wiki/Fly_ash
(fine particles that rise with the flue gases. Ash which does not rise is
termed bottom ash; often used to supplement Portland cement in concrete
production)
* Portland cement
http://en.wikipedia.org/wiki/Portland_cement
(the most common type of cement in general use around the world; developed
from natural cements made in Britain, and its name is derived from its
similarity to Portland stone, a type of building stone that was quarried on
the Isle of Portland in Dorset, England; patented in 1824)

(iii) WANG Lan/Cement and New Building Materials Research Institute under

(iv) The report said concrete blended with high-quality fly ash "can give
the tracks' concrete base a lifespan of 100 years," whereas that blended
with poor-quality fly ash "would mean China's high-speed rail tracks would
last only 50 years."

Quote:
"The Finance Ministry said last week that the Railways Ministry continued to
lose money in the first quarter of this year. The ministry’s debt stands
at $276 billion, almost all borrowed from Chinese banks.
"During February’s annual migration, officials noticed that the high-speed
trains were largely empty. But the slow trains on those lines have been
taken out of use, giving people few choices. As a result, the highways were
clogged and more people rode long-distance buses.
