On 3 June 1998, part of an [[ICE 1]] train on the [[Hanover–Hamburg railway|Hanover–Hamburg railway]] near [[Eschede]] in [[Lower Saxony]], Germany [[Derailment|derailed]] and [[Train wreck|crashed]] into an [[overpass]] that crossed the railroad, which then [[List of bridge failures|collapsed]] onto the train. 101 people were killed and at least 88 were injured<!--Different sources give the number of injured as 88, 105 or 119.-->, making it the second-deadliest [[Lists of rail accidents|railway disaster]] in German history after the 1939 [[Genthin rail disaster]], and the world's worst ever [[high-speed rail]] disaster.

The cause of the derailment was a single [[Fatigue (material)|fatigue]] crack in one [[Train wheel|wheel]], which caused a part of the wheel to become caught in a [[railroad switch]] (points), changing the direction of the switch as the train passed over it. This led to the train's carriages going down two separate [[Railway track|tracks]], causing the train to derail and crash into the pillars of a concrete road bridge, which then collapsed and crushed two coaches. The remaining coaches and the rear power car crashed into the wreckage.

After the incident, many investigations into the wheel fracture took place. Analysis concluded that the accident was caused by poor wheel design which allowed a fatigue fracture to develop on the wheel rim.<ref>{{Cite journal |last1=Fischer |first1=G. |last2=Grubisic |first2=V. |date=October 2007 |title=Praxisrelevante Bewertung des Radbruchs vom ICE 884 in Eschede |url=http://dx.doi.org/10.1002/mawe.200700151 |journal=Materialwissenschaft und Werkstofftechnik |volume=38 |issue=10 |pages=789–801 |doi=10.1002/mawe.200700151 |s2cid=109073127 |issn=0933-5137 }}</ref>
Investigators also considered other contributing factors, including the failure to stop the train, and maintenance procedures.

The disaster had legal and technical consequences including trials, fines and compensation payments. The wheel design was modified and train windows were made easier to break in an emergency.
A [[memorial]] place was opened at the place of the disaster.

== Background ==
{{Further|High-speed rail in Germany}}

The InterCity Express 1, abbreviated as [[ICE 1]], is the first German high-speed train and was introduced in 1988.

==Timeline==
[[File:401 551 AW Nürnberg.jpg|thumb|Rear power car ''401&nbsp;551'' of the crashed train]]

===Wheel fracture===
[[ICE 1]] trainset 51 was travelling as ICE&nbsp;884 "''[[Wilhelm Röntgen|Wilhelm Conrad Röntgen]]''" from [[Munich]] to [[Hamburg]]. The train was scheduled to stop at [[Augsburg]], [[Nürnberg]], [[Würzburg]], [[Fulda]], [[Kassel]], [[Göttingen]], and [[Hanover]] before reaching Hamburg.<ref name="Seconds">"Derailment at Eschede" ("High Speed Train Wreck"). ''[[Seconds From Disaster]]''.</ref> After stopping in Hanover at 10:30, the train continued its journey northwards. About {{convert|130|km|-1}} and forty minutes away from Hamburg<ref name="Seconds" />{{Rp|0:05}} and {{Convert|6|km|spell=in}} south of central Eschede, near [[Celle]], the steel [[Railway tire|tyre]] on a wheel on the third axle of the first car split and peeled away from the wheel, having been weakened by metal fatigue. The momentum of this caused the steel tyre to flatten and it was catapulted upwards, penetrating the floor of the train carriage where it remained stuck.<ref name="Seconds" />

The tyre embedded in the carriage was seen by Jörg Dittmann, one of the passengers in Coach 1. The tyre went through an armrest in his compartment between the seats where his wife and son were sitting. Dittmann took his wife and son out of the damaged coach and went to inform a conductor in the third coach.

The conductor, who noticed vibrations in the train, told Dittmann that company policy required him to investigate the circumstances before pulling the emergency brake. The conductor took one minute to reach the site in Coach 1. According to Dittmann, the train had begun to sway from side to side by then. The conductor did not show willingness to stop the train immediately, and wished to first investigate the incident more thoroughly. Dittmann could not find an emergency brake in the corridor and had not noticed that there was an emergency brake handle in his own compartment.<ref>"Eschede Zug 884".</ref> The train crashed just as Dittmann was about to show the armrest puncture to the conductor.<ref name="Seconds" />{{Rp|13:12}}

===Derailment===
As the train passed over the first of two points, the embedded tyre slammed against the guide rail of the points, pulling it from the railway ties. This guide rail also penetrated the floor of the car, becoming embedded in the vehicle and lifting the [[bogie]] off the rails. At 10:59 local time (08:59 [[UTC]]), one of the now-derailed wheels struck the points lever of the second switch, changing its setting. The rear axles of car number 3 were switched onto a parallel track, and the entire car was thereby thrown sideways into the [[pier (architecture)|piers]] supporting a {{Convert|300|t|adj=on}} roadway [[Bridge|overpass]], destroying them.<ref name="Seconds" />

Car number 4, likewise derailed by the violent deviation of car number 3 and still travelling at {{convert|200|km/h|mph|round=5}}, passed intact under the bridge and rolled onto the embankment immediately behind it, striking several trees before coming to a stop. Two [[Deutsche Bahn]] railway workers who had been working near the bridge were killed instantly when the derailed car crushed them. The breaking of the car couplings caused the automatic [[Emergency brake (train)|emergency brakes]] to engage, and the mostly undamaged first three cars came to a stop.<ref name="Seconds" />

===Bridge collapse===
The front power car and coaches one and two cleared the bridge. The third carriage hit the bridge, causing it to collapse, but cleared the bridge. Coach four cleared the bridge, moved away from the track onto an embankment, and hit a group of trees before stopping. The bridge pieces crushed the rear half of coach five. The restaurant coach, six, was crushed to a {{Convert|15|cm|4=0|adj=on}} height. With the track now obstructed completely by the collapsed bridge, the remaining cars [[Jackknifing|jackknifed]] into the rubble in a zig-zag pattern: car 7, the service car, the restaurant car, the three first-class cars numbered 10 to 12, and the rear power car all derailed and slammed into the pile.<ref name="Seconds" />{{Rp|34:25}} The resulting chaos was likened to a partially collapsed [[folding ruler]]. An automobile was also found in the wreckage; it belonged to the two railway technicians killed, and was probably parked on the bridge before the accident.<ref name="Seconds" />{{Rp|36:20}}

Separated from the rest of the carriages, the detached front power car coasted for a further three kilometers (two miles) until it came to a stop after passing Eschede railway station.

[[File:401 051 Eschede-Tk.jpg|thumb|Front power car 401 051 at Munich in August 2007. The power car coasted down the track until it came to a halt a short distance after Eschede railway station. Having sustained only minor damage during the accident, it was repaired and returned to service.]]

The crash produced a sound that witnesses later described as "startling", "horribly loud", and "like a plane crash". People living nearby, alerted by the sound, were the first to arrive at the scene; Erika Karl, the first, photographed the site. She said that, upon hearing the noise, her husband initially believed there had been an aircraft accident. After the accident, eight of the ICE carriages occupied an area slightly longer than the length of a single carriage.<ref name="Seconds" />{{Rp|34:20}}

At 11:02, the local police declared an [[Emergency management|emergency]]. At 11:07, as the magnitude of the disaster quickly became apparent and this was elevated to "major emergency". At 12:30 the [[Celle (district)|Celle district]] government declared a "[[Disaster#Transportation|catastrophic]] emergency" (civil [[state of emergency#Germany|state of emergency]]). More than 1,000 rescue workers from regional emergency services, fire departments, rescue services, the police and army were dispatched. Some 37 [[emergency medicine|emergency physicians]], who happened to be attending a professional conference in nearby [[Hanover]], also provided assistance during the early hours of the rescue effort, as did units of the [[British Forces Germany]].

While the driver and many passengers in the front part of the train survived with minor to moderate injuries, very few passengers survived in the rear carriages, which crashed into the concrete bridge pile at a speed of {{convert|200|km/h|abbr=on|round=5}}. 101 were killed, including the two railway workers who had been standing under the bridge.

ICE 787, travelling from Hamburg to Hanover, had passed under the bridge going in the opposite direction only two minutes earlier. That train had passed the bridge one minute ahead of schedule, while the accident train was one minute behind schedule. Had both been on time, ICE 787 may have also been impacted by the derailment.

By 13:45 authorities had given emergency treatment to 87 people, of whom the 27 most severely injured were airlifted to hospitals.

==Causes==
The disintegrated resilient wheel was the cause of the accident, but several factors contributed to the severity of the damage, including proximity to the bridge and flipping point, and the wheel being on a car near the front of the train, causing many cars to derail.

===Wheel design===
The [[ICE 1]] trains were originally equipped with single-cast [[Wheelset (rail transport)|wheelsets]], known as [[Train wheel#Railway wheel and tire|monobloc wheels]]. Once in service it soon became apparent that this design could, as a result of [[metal fatigue]]{{Citation needed|reason=''wear'' would make more sense here|date=April 2017}} and uneven wear, result in [[resonance]] and vibration at cruising speed. Passengers noticed this particularly in the restaurant car, where there were reports of loud vibrations in the dinnerware and of glasses "creeping" across tables.

Managers in the railway organisation had experienced these severe vibrations on a previous trip and asked to have the problem solved. In response engineers decided that to solve the problem, the suspension of ICE cars could be improved with the use of a rubber damping ring between the rail-contacting [[Railway tire|steel tyre]] and the steel wheel body. A similar design (known as resilient wheels) had been employed successfully in [[tram]]s around the world, at much lower speeds. This kind of wheel, dubbed a ''wheel–tyre'' design, consisted of a wheel body surrounded by a {{Convert|20|mm|in|adj=mid|-thick}} rubber damper and then a relatively thin metal tyre. The new design was not tested at high speed in Germany before it was made operational, but was successful at resolving the issue of vibration at cruising speeds. Decade-long experience at high speed gathered by train manufacturers and railway companies in Italy, France and Japan was not considered.{{Citation needed|date=April 2023|reason=was this wheel structure tested or used anywhere at high speeds?}}

At the time, there were no facilities in Germany that could test the actual failure limit of the wheels, and so complete prototypes were never tested physically. The design and specification relied greatly on available materials data and theory. The very few laboratory and rail tests that were performed did not measure wheel behaviour with extended wear conditions or speeds greater than normal cruising.{{Clarify|date=April 2023}} Nevertheless, over several years the wheels had been reliable and, until the accident, had not caused any major problems.

In July 1997, nearly one year before the disaster, [[Üstra]], the company that operates Hanover's tram network, discovered fatigue cracks in dual block wheels on trams running at about {{convert|24|km/h|mph|abbr=on}}. It began changing wheels before fatigue cracks could develop, much earlier than was legally required by the specification. Üstra reported its findings in a warning to all other users of wheels built with similar designs, including [[Deutsche Bahn]], in late 1997. According to Üstra, Deutsche Bahn replied by stating that they had not noticed problems in their trains.<ref name="Seconds" />{{Rp|39:38}}

The {{Interlanguage link|Fraunhofer Institute for Structural Durability and System Reliability|de|3=Fraunhofer-Institut für Betriebsfestigkeit und Systemzuverlässigkeit}} ([[Fraunhofer Institute|Fraunhofer]] LBF) in Darmstadt was charged with the task of determining the cause of the accident. It was revealed later that the institute had told the DB management as early as 1992 about its concerns about possible wheel–tyre failure.

It was soon apparent that dynamic repetitive forces had not been considered in the modelling done during the design phase,<ref>{{cite web |last=Griffith |first=Angela |title=Eschede Train Derailment |website=Root-Cause-Analysis.info |date=4 June 2009 |url=https://root-cause-analysis.info/2009/06/04/eschede-train-derailment/ |archive-url=https://web.archive.org/web/20230426104900/https://root-cause-analysis.info/2009/06/04/eschede-train-derailment/ |archive-date=2023-04-26 }}</ref> and the resulting design lacked an adequate margin of safety. The following factors, overlooked during design, were noted:
# The tyres were flattened into an ellipse as the wheel turned through each revolution (approximately 500,000 times during a typical day in service on an ICE train), with corresponding fatigue effects.
# In contrast to the monobloc wheel design, cracks could form on the inside as well as the outside of the tyre.
# As the tyre wore thinner, dynamic forces increased, causing crack growth.
# Flat spots and ridges or swells in the tyre dramatically increased the dynamic forces on the assembly and greatly accelerated wear.

===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}}

===Other factors===
The design of the overbridge may have also contributed to the accident because it had two thin piers holding up the bridge on either side, instead of the spans going from solid abutments to solid abutments. The bridge that collapsed in the [[Granville rail disaster]] of 1977 had a similar weakness. The bridge built after the disaster is a [[Cantilever bridge|cantilevered design]] that does not have this vulnerability.

Another contributing factor to the casualty rate was the use of welds that "unzipped" during the crash in the carriage bodies.<ref>{{cite magazine |title= |magazine=[[Modern Railways]] |date=December 2004 |page=16 }}{{Title missing|date=March 2025}}</ref>

==Consequences==

===Legal===
Immediately after the accident, Deutsche Bahn paid 30,000 [[Deutsche Mark]]s (about [[US$]]19,000) for each fatality to the applicable families. At a later time Deutsche Bahn settled with some victims. Deutsche Bahn stated that it paid the equivalent of more than 30 million U.S. dollars to survivors and the families of victims.<ref name="Seconds" />{{time needed|date=January 2017}}

In August 2002, two [[Deutsche Bahn]] officials and one engineer were charged with [[manslaughter]]. The case ended in a [[plea bargain]] in April 2003. According to the German code of criminal procedure, if the defendant has not been found to bear substantial guilt, and if the state attorney and the defendant agree, the defendant may pay a fine and the criminal proceedings are dismissed with prejudice and without a verdict. Each engineer paid [[€]]10,000 (around US$12,000).<ref name="Seconds" />{{time needed|date=January 2017}}

[[File:Sollbruchstelle ICE1.jpg|thumb|ICE 1 train window with predetermined breaking point and emergency hammer]]

===Technical===
Within weeks, all wheels of similar design were replaced with [[monobloc wheel]]s. The entire German railway network was checked for similar arrangements of switches close to possible obstacles.

Rescue workers at the crash site experienced considerable difficulties in cutting their way through the train to gain access to the victims. Both the [[aluminium]] framework and the pressure-proof windows offered unexpected resistance to rescue equipment. As a result, all trains were refitted with windows that have breaking seams.

==Memorial==
Udo Bauch, a survivor who was left disabled by the accident, built his own memorial with his own money. Bauch said that the chapel received 5,000 to 6,000 visitors per year. One year after Bauch's memorial was built, an official memorial, funded partly by Deutsche Bahn, was established.<ref name="Seconds" />{{time needed|date=January 2017}}

The official memorial was opened on 11 May 2001 in the presence of 400 relatives as well as many dignitaries, rescuers and residents of Eschede.<ref>{{cite magazine |last=Meldung |title=Gedenkstätte Eschede Eingeweiht |magazine=[[Eisenbahn-Revue International]] |issue=8-9 |date=2001 |issn=1421-2811 |language=de |trans-title=Eschede Memorial Inaugurated |page=341 }}</ref> The memorial consists of 101 [[Prunus avium|wild cherry trees]], with each representing one fatality. The trees have been planted along the rails near the bridge and with the switch in front. From the field, a staircase leads up to the street and a gate; on the other side of the street a number of stairs lead further up to nowhere.<ref>

== Dramatization ==
The Eschede derailment, as well as the investigation into the incident, was covered as the fifth episode of the first season of the [[National Geographic (American TV channel)|National Geographic]] TV documentary series ''[[Seconds from Disaster]]'', entitled "Derailment at Eschede" which was filmed on the [[Ecclesbourne Valley Railway]] in Derbyshire, UK.<ref name="Seconds" />
