Are they referring to the plastic (or whatever it is) sheet that is
hooked between each car? I thought these were to prevent people in
particular the blind falling onto the tracks from the platform.

That and train surfing, IIRC. However there are supposed to be inner
barriers as well to make things safer for people passing between cars via
the end doors.

The RMT seem to be suggesting that the design doesn't work for 12 year old
boys - back to the drawing board maybe?
