HK high-speed train collision scenario analysis under question

It will be like a small van being hit by a heavy truck if the trains acquired by MTR Corp (00066.HK) for the Guangzhou-Shenzhen-Hong Kong Express Rail Link collide with the trains of Guangzhou.

The MTR’s nine CRH380A high-speed trains will share the same rail tracks with the nine CRH3 trains acquired by its Guangzhou counterparts, Apple Daily reported Wednesday.

However, the CRH380A can only withstand collisions of 10 km/hr, and it only weighs 388 tons because lightweight aluminum alloy was used in order to enhance the speed.

In comparison, Guangzhou’s CRH3 is an European model and can withstand collisions of up to 36 km/hour. It weighs 447 tons, 13 percent heavier than the CRH380A, the report said.

Albert Lai, chairman of The Professional Commons, said it will be like a small van being hit by a heavy truck if the two collided.

“Obviously, the heavy truck will have less damage while the small van will be devastated and there is a good chance that it will derail,” he said.

Lai cited the Wenzhou train collision in 2011, in which a lighter Japanese model CRH2 hit a heavier European model CRH1. The CRH2 suffered more severe damage than the CRH1.

The Electrical and Mechanical Services Department has said that the MTR collision analysis report only analyze the safety performance when two trains of the same model hit each other.

Lai criticized the MTR for evading core problems, pointing out the hidden dangers in train safety as Hong Kong will have a lot more different train models and many high-speed trains from various mainland cities will come to Hong Kong.
