The Service Team was on site on 16 & 17 Jan trying to rectify the problem. It looks like it was not an easy task as a lot of man hours had been put in. This is consider a relatively new escalator as run time is only less than 6 months. The repair had been completed and open for public usage.
The quality of escalator is very important. Fujitec and Kone usually can rectify their escalator in a timely manner. They only spend more man days when doing preventive maintenance. HDB need to review the operation and quality of IFE before they made subsequent purchase for their other projects or have alternative suppliers.
