BEIJING, Feb. 4 (Xinhua) -- China will carry out a special campaign to check potential safety problems of high-speed trains this year, the country's work safety supervision authorities said.
The State Administration of Work Safety said in a statement on its website that it will work with the Ministry of Railways to have a safety overhaul.
On July 23, 2011, a high-speed train rammed into a stalled train near the city of Wenzhou in east China, leaving 40 people dead and 172 injured.
The decision of safety overhaul was made in accordance with the instructions given in an investigation report released in December by the State Council after the disastrous high-speed train crash.
The overhaul will cover high-speed railway signaling system, maintenance of trains, lightning-proof designs, employees' training and operating environment, the statement said.
