The 2006 Zoufftgen train collision occurred around 11.45 am on 11 October 2006, near

double track
line was out of service for maintenance. Six people, including the drivers of both trains, were killed: two Luxembourgers and four French. Twenty more were injured in the accident, two seriously.

Circumstances

Aftermath of the accident

One train was a

Bâle – ThionvilleBettembourg route. They were involved in a head-on collision.[1] This type of accident, called nez-à-nez ("Nose to Nose") in French railway jargon, is relatively rare and often fatal. One of the most fatal head-on collisions in France was the 1985 Flaujac train collision, which left 35 dead and 120 injured. The most recent accident of this kind happened on the Tende line
on 27 January 2003 where a French and an Italian train collided, killing both drivers.

The accident occurred between the border stations of

double track
section. The accident was on a section crossing a forest, limiting visibility. The speed limits of the trains were 140 km/h (87 mph) and 100 km/h (62 mph).

Only a single track was being used because of engineering works. The line was

25 kV AC, and equipped, between Thionville and Bettembourg, with BAL (bloc automatique lumineux, "automatic signal blocks") and IPCS (installation permanente de contre-sens, "permanent counter-track installations") which allow trains to run in one or other direction, the signalling and the interlocking being preconfigured to achieve this. Both trains were equipped with safety systems, KVB (contrôle de vitesse par balises
, "Speed control by beacons") on the French side and Memor II+ on the Luxembourg side, which in particular halts the train if it passes a stop signal.

Response

The

emergency plan
) to organise the response. Hundreds of French and Luxembourger rescue workers were marshalled:

The "

Red plan
" was lifted two days after the accident, shortly after the sixth and last victim had been extricated.

Investigations

Preliminary

According to the preliminary investigation, validated by the prefecture of the Department of Moselle and the Luxembourg authorities, the accident had caused:

  • Six deaths, two Luxembourgers and four French, being the drivers and a worker on the adjacent track
  • Two serious injuries (both French), removed to Thionville and Luxembourg for treatment
  • Fourteen minor injuries or shock, treated in Thionville and Luxembourg.[2]

Inquiries

The accident being in both France and Luxembourg, judicial inquiries were opened by the authorities in both

CFL
and the Entité d'Enquête d'Accidents et d'Incidents ("Inquiry Agency for Incidents and Accidents"), in concert with the BEA-TT.

On 8 October 2007, the court of the

actual bodily harm
. After investigation, indictments of two board members of the CFL were dropped. While no individual has been identified, it was stated that among the accused were two traffic controllers.

Later

After further investigations by SNCF and CFL, railway officials came to the conclusion that the fault lay with the Luxembourg rail traffic controllers who cleared the passenger train onto the same track as the freight train. Luxembourg's Transport Minister Lucien Lux was quoted as saying "It's tough to say, but it's the fault of the CFL."[3]

Analysis

The Luxembourger driver of TER 837 617 received an order to pass a red (stop) signal to enter the zone operated by freight train number 45 938, pulled by SNCF Class BB 37000 locomotive 37007 from the Thionville depot, which had entered the section as normal by passing a green signal.

The accident was due to a human signalling error on the Luxembourg side, according to information from the Luxembourg Minister of Transport on 15 October 2006.

The CFL accepted that the double-deck passenger train (

TER train to proceed on the track past a red signal which had already cleared the freight train from the opposite direction.[4]

Having realised the mistake, the signaller at Bettembourg triggered an alert by RST (Radio sol train, "Train Radio System"), which was not received by the driver of the passenger train. He then wanted to cut the electricity supply for the line, but this was not possible because of the different

rail electrification
systems of the two countries; moreover the Luxembourg train had already passed to the French side, and so was beyond the signaller's control.

Crumple zones

The Class 2200 rolling stock was extremely new (2004) and had crumple zones that progressively collapsed in the event of overriding (locomotive BB 37007 going under the CFL locomotive).

The cab of locomotive BB 37007 was destroyed by the force of the collision, but the rest of the leading structure remained "coherent". The crumple zone had been compressed. The driver, stuck in the cab, had no escape. The trailing wagons left the track to the right (in the direction of the train) after their couplings failed.

The head motor car of the CFL train, built on the same assembly line as the SNCF train, had had its cabin crushed by the force of the collision and the roof was torn off by the overriding locomotive; however the intermediate trailing wagons and the tail motor car remained on the track, because the ends of each of the cars in between had anti-override structures which "locked" against each other in case of shock. These structures led to the high number of survivors.
