High speed was one of the factors causing the deadly train disaster in Zibo, Shandong Province, Xinhua said on Tuesday.
The Monday train collision killed at least 71 and injured 416 others by the time of press. It occurred when a passenger train from Beijing derailed and collided with an oncoming train on the Jinan- Qingdao line. Xinhua reported that the train from Beijing was traveling at 131 kilometers an hour, in excess of the 80-kilometer-an-hour speed limit, before it came off the tracks.
Authorities had on Monday ruled out terrorism and said "human error" was to blame.
In 2006, China made up a quarter of the world’s total railway transport volume, while its track length only made up six percent of the world’s total, according to the Ministry of Railways.
On such busy tracks, a small error can cause chaos. The Zibo accident is the worst in China since 1997 when 126 people were killed in Hunan Province.
That year coincided with the decision to raise train speed limits in China. In 1997, most trains were running at a mere 60 kilometers per hour. Last April, China boosted its railway speed for the sixth time raising the top train speed by 25 percent to 200 kph.
Necessary safety measures were adopted prior to the speedup. For example, on lines that carry trains traveling at 160 kph or faster, protective nets were erected on both sides to prevent animals or people from being "sucked" on to the tracks.
But still there are problems according to experts. One is that China doesn’t have a special track system for passenger trains, which have to run with the comparatively slow freights. This not only reduces the efficiency of the whole transportation system but also jeopardizes safety. High-speed trains require more sophisticated tracks with regards to steel strength and engineering structures.
The 384km Jinan-Qingdao line will soon solely be used for freight. A special line for passenger trains will be finished before the Olympics.
Zang Qiji, a ministry researcher, said that most track beds in China were designed for speeds of 120 km/h, and were upgraded to 160 km/h in 1998. Some still lack the capability to handle speeds of 200 km/h.
However, train travel is still comparatively safe in China. The accident rate on railways is 1/24 of China’s highway. According to the ministry, deaths on the track declined by 43. 8 percent in 2007 compared with figures from 2006.
Human error is the primary cause of accidents, according to a survey from 1989 ～ 2001 published by the periodical Railway Transport and Economy. About 64.6 percent of track accidents were caused by human errors, while 13.8 from natural disasters, 12.3 by social unrest. Only 9.2 percent were caused by facilities.
