the speed i not sure
but for the door, it always liek this
train door open first , then open the station door
all the while since train start is like this alreayd.
u dunno meh?
the PSDs are opened longer than usual after the train doors open
now. the previous times that i have taken NEL, the train doors open
already, the PSDs would almost be opened. now, train doors open
already, PSDs have to wait until 1 or 2 seconds then open, except
some trains. also, after the doors closing announcements, the train
doors of some C751A are not closed until 1 or 2 seconds later.
previously, C751 train doors would already be closed after the "de
de" sounds from the doors closing announcements.
