China South Locomotive and Rolling Stock Corp Ltd (CSR) has signed contracts worth of 6.89 billion yuan ($1.07 billion) to build subway and passenger vehicles, the company said on Thursday.

The contracts, signed by its two units, account for 10.6 percent of its revenue last year, the company said in a filing to the Shanghai Stock Exchange.

Shanghai-listed shares of CSR were trading up 1.2 percent at 5.92 yuan on Thursday after slumping over 10 percent this week following a deadly train collision between two high-speed trains. Both trains were made by joint ventures of CSR.
