An AWS magnet, which stops the train if it passes a non-green signal
without the driver pushing a button to acknowledge it:

To the left of it there may have been a TPWS grids, which do much the
same thing, but are more sophisticated:

Thanks for the info :-)
I didn't notice a grid but I'm there again tonight so will look, I
expect it's a similar setup in all stations anyway?

And almost all platforms have a signal at the end, and every signal
has an AWS ramp, so you should see them everywhere. TPWS has only been
fitted where there's a high-than-usual risk, but you see them quite
often in stations. They're used in termini to stop trains going too
fast towards the buffers, which AWS can't.
