「行車管理電腦」切換 “Changeover” of Train Controlling Computers
凌晨兩點正，港鐵各行車綫的「行車管理電腦」需要進行切換，避免系統因長時間運作超載
列車到站後，車門會稍後再打開； 停緊站嘅列車，都需要等切換完成先可以開出，或者月台門可能會突然閂埋一陣
坐緊港鐵通宵服務嘅你，麻煩等一等啦
Train Controlling Computers will perform “changeover” at 0200 hours to prevent system overload
During this operation, train doors may not open immediately upon arrival
Trains already berthed at platforms may be held until the changeover is finished. Platform doors may be closed for a short while without notice
Thank you for your patience
