If I read the description correctly, those hardware level systems were manually overridden, which should only be done in extremis. My guess is that this is going to turn into a normalization of deviance case, since such a cavalier attitude toward safety was unlikely to be one person's first time doing something so dangerous. There was no dilemma here and no time pressure.

Your suggestion about limiting speed after a shut down is a good one. On top of that, the rail operators should have spotted a trend of repeated safety system overrides and investigated why that was happening.
