The MTR Corporation said “minor cracks” on train roofs were discovered in 2013, but had no impact on passenger safety.
On Wednesday, the corporation responded to online rumours about deformed roofs of trains currently serving the East Rail Line, West Rail Line and Ma On Shan Line. Also known as SP1900, the trains were manufactured by Japanese companies Itouchu, Kinki Sharyo and Kawasaki Heavy Industries. The MTRC said cracks were caused by chemical reactions of insulating materials under high temperatures, Apple Daily reported.
As suggested by the manufacturer, the MTRC covered the cracks with insulation paint in order to enhance the train’s ability to withstand temperature changes. The corporation added that small bulges were found on roofs of the same train model in 2002, but the situation was improved after applying layers of insulation paint.
The Electrical and Mechanical Services Department confirmed that the cracks did not damage train structure and would not affect railway safety.
