Yup, any controller can set a signal to red (that’s how we do track blocks, said clips are the backup to that because you always want the dude in the sky to know you’re there).
Not all trains have kit to stop a SPAD, unless you meant specifically in the instance of the operator involved in this incident. Some do, but it’s absolutely not universal around the world. For example, Automatic Train Protection (ATP) can do this, but it requires both a track-side magnet and the rolling stock to have the kit for it. We use that to trigger our driver vigilance system acknowledgement when approaching suburban passenger stations. Failure to acknowledge the vigilance prompt will throw the brake to emergency and stop the train.
That said, it’s absolutely not present out in the Wild West of freight (because maintaining that many ATP magnets is insanely prohibitive).

For information specific to Norway (in Norwegian) there is a lot here:
All trains have instrumentation which will cause them to stop if they pass a red signal.
The gritty details appear to be in the Togframføringsforskriften, however this has been repealed a couple of years ago, presumably to bring us in line with EU regulations - but I am too tired to try to figure this out tonight, though I have always been a sucker for figuring out how signalling systems work...
