Happens all the time at Aldwarke Jn. Trains off Rotherham Central going down the Thrybergh branch, and a train on the Down Main.

What on earth did he do that for?
At Wickford (Essex) many moons ago the signalman found that he could pull a lever when he shouldn't have been able to. He called the technician who expressed doubt - so the signalman showed him and promptly derailed a train.

In mechanical interlocking, even without a track circuit facing points are often locked (in addition to the facing point lock) by a 'fouling bar', which sits in the flangeway and prevents the fpl being taken out to unlock the points.
It should be long enough to span between bogies, but in practice it is often a bit shorter.
Note this is all secondary protection: any signal cleared across the s&c will lock the pints in their position, and the fpl too. The fouling bar prevents the fpl being taken out even if the signals are put back, if a train is close/on the s&c. And on most modern (or modernised) mechanical installations there will be track circuits and approach control (places a timeout lock on the s&c if the signal is put back in face of a train, so the train can stop in the originally safely set path) anyway. So never any real chance of points being moved unsafely in advance of a train, even in older mechanical installations.

Was that similar to the one at guide bridge where the signal man tried to beat the interlocking?
Probably this one https://www.railwaysarchive.co.uk/documents/DoE_Audenshaw1970.pdf

There was a fatal derailment at Connington South, near Huntingdon on the ECML, in 1967 in which it appears a young signalman (aged 20) deliberately moved the points under a train (possibly with the intention of moving them to "reversed" and back to "normal" between the passage of the two bogies of one carriage over them, to prove that he could?)

The mind boggles why someone would want to do that.

We were told about Connington during my signalman’s training course at Beckenham. I gather that some very pointed correspondance had passed between BR and the Royal Marines after the inquiry.
