You were probably supposed to bribe the the border people. That would probably have worked even if that is not what they expected.
I have noticed the Thai 158s drive around with the doors open. They also seem to be formed up of 2 or more driving coaches so I guess the individual coaches can be coupled/uncoupled at will.
This is also true of the UK sets, hence the 3-car 'hybrids' with FGW; ours just look neater since the corridor connection is sealed.
