我哋今年會著手喺早期引入嘅列車車門安裝哩啲「靜音氣墊」。當車門關上後，膠邊會充氣，填補車身同車門之間嘅空罅，令車門更隔音。(純音樂) The door seals will expand after the train doors have closed to insulate the in-cabin environment from external noise. (Music Only)
The seals are not designed to make the door close quieter. The seals inflate after the door closes to seal the door gap so its quieter when its travelling.
