Fixed-asset investment in China's railway sector fell 36.1 percent year-on-year to 177.75 billion yuan ($278.68 billion) in the first half of this year, 100.37 billion yuan less than the same period in 2011, according to the Ministry of Railways.

Investment in railway infrastructure amounted to 148.71 billion yuan, down by 38.6 percent year-on-year.

The data suggests that fixed asset investment and infrastructure investment continued a declining trend as of June 2011, Securities Daily reported.

However, fixed-asset investment hit 48.1 billion yuan in June 2012, a new high for the year.

Investment in infrastructure reached 43.23 billion yuan also in June, another new high.
