Sorry, I'm still failing to see how someone rough-sleeping on a bench is in anyway comparable to blocking a road and obstructing travel. The actual equivalent would be laying across the track... which is not what's happening. I have seen disturbing images of places who so acutely fail to support their homeless populations that they have no other choice than to sleep in the roads, but even then they're up against the curb, not actually blocking the road.

At this point, I'm beginning to think you consider the mere presence of a rough-sleeper at a train station to be blocking the use of that train station, regardless of what it is they're actually doing.
