HK shares sag after rallying, China Railway gains

(Updates to open)

HONG KONG, March 13 (Reuters) - Hong Kong stocks fell on
Thursday, as weak mainland and U.S. equities prompted investors
to lock in profits a day after shares rose sharply.

But shares of China Railway Construction (1186.HK: Quote, Profile, Research, Stock Buzz) climbed in
their debut as investors chased the railroad builder on
expectations that China will continue its infrastructure spending
spree.

The benchmark Hang Seng Index .HSI opened down 2.1 percent
at 22,925.42. The China Enterprises Index of Hong Kong-listed
mainland companies .HSCE, or H shares, was down 2.7 percent at
12,531.58.
