NRC had a spate of these a few years ago, containers moving in traffic.

The twistlocks can work loose if not secured properly, likewise its a very
easy thing for a someone along the way (whilst a train sits in a siding
crossing trains) to unlock a few if they know what they are doing, (and most
vandals could workout how to do it). Then again, it may have been missed
during train examination?? Who knows??
