Tragedies in Norway and China

Two tragedies have shaken the world last week.
In one of them, on 22 July, a man detonated a bomb at a building in the centre of Oslo city, and then shot a number of young and unarmed men and women in the near-by island. He is currently under arrest.
When the first report of the incident came, the media reported that the Islamic connection might be suspected, as Norway is a NATO member and as such has sent troops to Iraq and Afghanistan, and also participated in the bombing of Libya. It seems nothing is further from the truth.
The arrested man, who is a white and is said to belong to an extremist right wing, has said that he has been reading Nazi literature, and is against the immigration policy of the country which is, to him, tolerant of the Muslims. He wanted to start a revolution by his terrorist action.
The media should have known, and we should have known, that Oslo is a city which is known for the Oslo Agreement of 1993 reached by the PLO and the Israeli Government. It was a time when the Middle East peace seemed to be nearer than at any other time till now. It came to a stalemate with the assassination of the Israeli Prime Minister Rabin in 1995. He was shot by a law student at Tel Aviv, an Israeli himself.
Then there was a clash of high-speed trains in China on 23 July. They were the pride of the country. The high-speed trains' network began to be laid down in 2007, in the year before the Beijing Olympics, just as the first Japanese Shinkansen(new trunk line) was first put to use in 1964, the same year as the Tokyo Olympics. But China's network has been widening at an amazing speed. It is now approaching 10,000 kms and is planned to reach twice that length in the near future.
I have often thought of travelling in this high-speed train in China as a tourist. So I am interested to know, for example, if the train is not able to run under a torrential rain with thunders, if there is no mechanical equippment to prevent a second train from nearing in the same tracks, and so on. Above all, how is one going to make out when it is reported, with photographs, that the four carriages of the second train which have clashed into the standing one from its rear on a bridge have been cut into pieces and buried in the ground, including the 'cockpit' itself. Have they searched for the survivors? Are they in a better position to examine the cause of the tragedy this way?
Looking at the network of thses high-speed trains, I also wonder if they are mostly for the purpose of linking more closely the areas already developed, rather than linking the underdeveloped interior ones to them. If so, though I may be wrong, the network will widen the gap which is already existing.
