===2015 Eckwersheim accident===
{{Main|Eckwersheim derailment}}
On 14 November 2015, a specialised [[TGV Duplex#Dasye and Euroduplex|TGV EuroDuplex]] was performing commissioning tests on the unopened second phase of the [[LGV Est]] high-speed line in France, when it entered a curve, overturned, and struck the [[parapet#bridge parapet|parapet]] of a bridge over the [[Marne–Rhine Canal]]. The rear [[power car]] came to a rest in the canal, while the remainder of the train came to a rest in the grassy median between the northern and southern tracks. Approximately 50 people were on board, consisting of SNCF technicians and, reportedly, some unauthorised guests. Eleven were killed and 37 were injured. The train was performing tests at 10 percent above the planned speed limit for the line and should have slowed from {{convert|352|km/h|abbr=on}} to {{convert|176|km/h|abbr=on}} before entering the curve. Officials have indicated that excessive speed may have caused the accident.<ref name="RG">{{cite news|title=Test train catastrophe on LGV Est |url=http://www.railwaygazette.com/news/high-speed/single-view/view/test-train-catastrophe-on-lgv-est.html|access-date=16 November 2015|work=Railway Gazette|date=16 November 2015|archive-date=17 November 2015|archive-url=https://web.archive.org/web/20151117015359/http://www.railwaygazette.com/news/high-speed/single-view/view/test-train-catastrophe-on-lgv-est.html|url-status=dead}}</ref> During testing, some safety features that usually prevent accidents like this one are switched off.
