This really worries me, as it would seem that someone on the inside, e.g guard or attendant, are in on the scam; as a key would need to have been used. Some time ago we purchased a wedge that had an alarm built into it. We would place the wedge carefully under a door, and when further pressure was exerted on the wedge, by the door being opened, a piercing noise was the result. Although we have never tried it on a train, I would imagine that it work just fine.
