An Horrible Train

After service interruption on Tseung Kwan O line , MTR has present to you with another accident - The open of train doors when the train moved .

Here's are the time-line of the event :

2102 I enter Sha Tin station and I went to platform 2 , a train departured and I miss it .
( Around ) 2107 An SP1900 EMU (a.k.a. Millennium Train) arrive which bound for Lok Ma Chau , I got up and went back to home .
2109 The train arrived at Fo Tan and it is departured (as the doors are already closed and it started to move ) ...
Then ... AWWWWWWWWWWWWWWWWWWWWWWWWWW
THE TRAIN DOORS OPEN !
Then the train stop immedialy ( Maybe someone has pressed the emergency stop button )
2110 We are waiting and waiting ...
2111 Announcement has made - All passengers must leave the train as the train end its services . Whooo... The story ends .

I took a look on the car number where I took , and it said
H218
Good number , isn't it ?
( According to wikipedia , The whole train configurations are as follow :
D217 - P217 - M217 - H217 - C218 - H218 - M220 - P220 - F219 - M219 - P219 - D219
And I stand on D5 door on H218 )
