Editing Eschede train disaster (section)

===Maintenance===
About the time of the disaster, the technicians at Deutsche Bahn's maintenance facility in Munich used only standard flashlights for visual inspection of the tyres, instead of metal fatigue detection equipment.<ref>090120 NGC Seconds from the catastrophe{{Full citation needed|date=January 2017}}</ref> Previously, advanced testing machines had been used; however the equipment generated many [[false positive]] error messages, so it was considered unreliable and its use was discontinued.

During the week prior to the Eschede disaster, three separate automated checks indicated that a wheel was defective. Investigators discovered, from a maintenance report generated by the train's on-board computer, that two months prior to the Eschede disaster, conductors and other train staff filed eight separate complaints about the noises and vibrations generated from the [[bogie]] with the defective wheel; the company did not replace the wheel. Deutsche Bahn said that its inspections were proper at the time and that the engineers could not have predicted the wheel fracture.<ref name="Seconds" />{{time needed|date=January 2017}}
