ICE Eschede Accident in ZDF-TV Today: Die Todesfahrt des ICE 884

A report will be broadcasted via ZDF-TV at May 6., 20:15 - 21:25.
More background of the broken wheel will be presented with a main focus
on the question "was it possible to prevent this accident",
according to a ZDF-TV preview [1][2].
Obviously it will not be very technical, but in respect to responsibility
and ethics of NDT, it's may be worthwhile to see it.

I was contacted a lot during the days after the accident in May 1998 from
a ZDF-TV journalist, however, so far no information had been broadcasted.
Only Focus-TV broadcasted our interview /news/1998/bahn_tv.htm.
In one of my former comments I suspected that ZDF-TV was manipulated by
the railway lobby [2].
It will be interesting to see today if now objective information will be shown.

In a coincidence of this topic some railway news are part of this month's issue,
e.g. "Continuing Railway Accidents Show the Importance of NDT".

Re: ICE Eschede Accident in ZDF-TV Today: Die Todesfahrt des ICE 884
I would like to inform you about the essential findings the TV report mentioned.

- With a wrong construction of the traveling gear (axle) the problems started.
- Mono-block wheels have been replaced in an early stage because of to much vibrations.
- The new wheel with a ring and rubber attachment was a safety risk.
- The Deutsche Bahn knew about the safety risk (inner surface fatigue cracks),
however did not applied appropriated in-service inspections e.g. ultrasonic testing.

The report did NOT mentioned that the DB recognized the weakness of its in-service inspection,
however, developed a wrong concept (ultrasonic surface wave method).

mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
