China CNR Corp Ltd has recalled 54 bullet trains used on the Beijing to Shanghai line for safety reasons.
This follows the high speed crash last month that left 40 dead and over 200 injured.
The government’s handling of the crash triggered bold media coverage and public outrage.
Railway officials have blamed design flaws in the rail signal equipment as the cause of the accident.
The Minsitry of Railways also put a halt to further high speed projects whilst the crash is being investigated.
Operational bullet trains will run 40 to 50 kilometers below their top design speed as a safety precaution. The fastest speed one of these high speed trains is currently around 350 km p/h.
