Another High Speed train Crash due to broken wheel

Yesterday, another High Speed Train crashed in the United Kingdom. The
cause of the crash was a broken wheel.
This time, fortunately, there appear to be no serious injuries.

The wheel broke when the train was travelling at 100 mph (160 kph).
All trains of this type have been withdrawn from service until the
wheels have been tested with ultrasonics.

DONT THE RAILWAY COMPANIES READ THE NEWSPAPERS ?
This is an ocurrence that should have been prevented after the tragedy
of a few days ago in Germany.
It is time that ALL RAILWAY COMPANIES assessed the situation and
considered an IMMEDIATE 100% check on wheels of High Speed Trains.

I shear Godfrey Hands' concerns in the mismanagement of safety in
transportation. Also here in Germany a few days ago other occurrences of
the same type of wheel which broke already months ago sudenly received
attention. But why first a tragedy must happen before such occurrences
get enough attention?

See on the Internet http://bst-tsb.gc.ca/raillist.html
We may learn from this Transportation Safety Board in Canada.
On this server are documents of occurrence investigation reports.
For example you can find in one report: ..... inadequate inspection
practices/equipment to detect slid-flat wheels; and the lack of emphasis placed
on safety inspections of passenger train brakes. (also pictures of broken wheels)

We, the NDT community, are obviously not in the position to control all those
necessary actions - it is out of our sphere.
However, we can work on public relations, with help of the media,
getting the attention from responsible authorities.
