Sudden heart attack kills signaling company head

BEIJING - The head of a State-owned railway company, which designed the flawed signaling equipment that caused the July 23 train crash near Wenzhou, died from a heart attack on Monday.

His death coincided with an announcement made by investigators who said they plan to soon begin identifying the persons or businesses that were responsible for the crash, which killed 40 people and left nearly 200 injured.

Ma Cheng, 55, the general manager of China Railway Signal and Communication Corp, died from a heart attack in Shenzhen when he was conducting a safety inspection on the new Guangzhou-Shenzhen passenger railway, according to an obituary notice posted on the company's website on Tuesday.
