The '''Lathen train collision''' occurred on 22 September 2006 when a [[Physics:Transrapid|Transrapid]] [[Physics:Magnetic levitation|magnetic levitation]] (or "[[Physics:Maglev|maglev]]") [[Engineering:Train|train]] collided with a maintenance vehicle near Lathen, {{wipe|Germany}}, killing 23 people.  It was the first [[Biology:Death|fatal accident]] involving a maglev train.

==The Transrapid==
[[Image:Transrapid.jpg|thumb|188px|File photo of a Transrapid train on its test track]]
The Transrapid 08 was still doing trial runs but would sometimes carry passengers along the {{convert|31.8|km|mi|adj=on}} test track to demonstrate the maglev technology.<ref name="BBC">[http://news.bbc.co.uk/1/hi/world/europe/5370564.stm "Deadly crash on German monorail"]. BBC News. 22 September 2006. Retrieved 23 September 2006.</ref> The Emsland test track runs from Lathen, near where the accident occurred, north to Dörpen, with a loop at each end and a depot side track near the southern loop. Speeds of up to 450&nbsp;km/h (280&nbsp;mph) are reached on the test track.<ref name="BBC"/>

Maglev trains use powerful magnets to hover {{convert|1|cm}} above the tracks.<ref name="Bloomberg"/>

==The accident==
Every morning a wheeled, diesel-powered maintenance vehicle ran along the tracks to check them for debris. When its work was finished it would wait in front of the last switch. There were two workers on the maintenance vehicle. They radioed the line dispatcher for clearance to leave the track but did not get a response. They were unaware of a test run scheduled that morning half an hour earlier than usual. The test run was carrying visitors from associated companies, including employees at Transrapid, workers from a local nursing care company, and workers from local utility company RWE.

The maglev train was boarded according to usual routine. It left the station at 09:43 and firstly went for a brake test, then had to wait for clearance from the line dispatcher. The line dispatchers energized the tracks at 09:52 and one line dispatcher radioed the maglev train to proceed. No communication with the maintenance vehicle is recorded. The train rapidly accelerated to the 170&nbsp;km/h that was common for the first test round before the 450&nbsp;km/h on the subsequent test rounds.

[[File:Transrapid-Werkstattwagen.png|thumb|Maintenance vehicle in normal operation]]
The train started moving at 09:53, and 57{{nbsp}}seconds later emergency braking was recorded. Approximately half a second and 25{{nbsp}}metres later the maglev train hit the maintenance vehicle at a speed of 162{{nbsp}}km/h. The aerodynamic design of the Transrapid train caused it to dive under the 60-tonne maintenance vehicle, ripping off the roof of the maglev train. The wreckage continued for another 300 metres on the track before coming to a halt.

There were 23 fatalities and 11 injuries, 10 severe.<ref>[http://www1.ndr.de/ndr_pages_std/0,2570,OID3129340_SPC3131186,00.html "Ermittlungen nach schwerem Transrapid-Unfall im Emsland"] {{Webarchive|url=https://web.archive.org/web/20060925094036/http://www1.ndr.de/ndr_pages_std/0,2570,OID3129340_SPC3131186,00.html |date=25 September 2006 }}. NDR Online. Retrieved 23 September 2006.</ref> The two-man crew of the maintenance vehicle were among the survivors as they were at the opposite end of the vehicle. Three survivors from the Transrapid were rescued by removing the bottom panel when they were heard knocking underneath. Two engineers sitting in the rear section of the maglev survived, and three other passengers were saved later by cutting through the remains of the maglev train. None escaped unscathed.

==Emergency response==
Firefighters used turntable ladders and aerial platforms to reach the wreckage {{convert|4|m}} above ground level.

==Immediate aftermath==
Immediately after the accident, German transport minister Wolfgang Tiefensee held an emergency meeting with representatives from Siemens AG and [[Company:ThyssenKrupp|ThyssenKrupp]], the two companies jointly responsible for the Transrapid. He commented afterwards that "major safety failings" were the clear cause of the accident, and that two key questions requiring answers were whether the Transrapid's safety measures were adequate, and whether they were applied on the test track.<ref name="terra"/> He also promised an independent inquiry.<ref name="terra"/>

==Investigation==
German authorities conducted an investigation into the accident. Rudolf Schwarz, head of operators at test track operator IABG, said, "This accident would not have been possible if all regulations were adhered to." According to IABG, the crew of the maintenance vehicle, which clears the test track of debris and dirt every morning, was supposed to radio the line dispatcher once the work was finished. German police therefore suspected human error as the likely cause of the accident. Prosecutors obtained and examined radio transcripts from the vehicles involved.<ref name="BBC"/>

In May 2008, a court in Osnabrück concluded that the tragedy was caused by a chain of human errors, including the failure to set an electronic braking system that would have prevented the train from operating while maintenance work was being carried out. Two staff members were found guilty on 23 counts of manslaughter and 11 counts of causing negligent injury and were fined 24,000 and 20,000 euros respectively. The line dispatcher who radioed the clearance to the maglev train was unable to take part in the trial because of suicide fears.<ref name="Bloomberg">{{cite web | title = German Court Fines Two Transrapid Supervisors After Fatal Crash | url = https://www.bloomberg.com/apps/news?pid=newsarchive&sid=aOU9MgAJN2eY&refer=germany | date = 2012-07-21 | archiveurl = https://archive.today/20120721113011/http://www.bloomberg.com/apps/news?pid=newsarchive&sid=aOU9MgAJN2eY&refer=germany | archivedate = 21 July 2012 | access-date = 22 March 2018 | url-status = live }}</ref><ref>{{cite web | title = Two convicted for German Transrapid deaths |work=Independent Online|location=South Africa| url = http://www.iol.co.za/news/world/two-convicted-for-german-transrapid-deaths-1.401741#.UBzo_ago9Rw | date = 2012-08-04 | archiveurl = https://archive.today/20120804091907/http://www.iol.co.za/news/world/two-convicted-for-german-transrapid-deaths-1.401741%23.UBzo_ago9Rw#.UBzo_ago9Rw | archivedate = 4 August 2012 | access-date = 5 March 2018 | url-status = live }}</ref> The trial of the two line dispatchers both resulted in convictions and prison sentences of one year and six months in one case, and one year in the other.

One year after the accident, a memorial stone was installed at the crash site.
