"CCTV footage has been released of a cyclist being hit by a high-speed train in Poland in a bid to show the dangers of ignoring red lights and barriers at level crossings."
Yes, that was the problem - CCTV footage not released before.
But that would have as much effect on a cyclist as a red traffic light!
Seriously, these half barriers pose no real barrier to someone determined to get past. They are, I think, above all a clear indication of not to proceed. Some people, however, do not possess the common sense to realise the dangers.
