2012 Sloterdijk Train Collision

On 21 April 2012 at 18:30 local time (16:30 UTC), two trains were involved in a head-on collision at Westerpark, near Sloterdijk, in the west of Amsterdam, Netherlands. Approximately 117 people were injured, one of whom later died in hospital. The collision is thought to have been caused by the driver of one of the trains passing a red signal.

Accident

In the early evening a local train (an NS Sprinter Lighttrain) had just left Amsterdam Centraal and collided with a double-decker NS VIRM Intercity train travelling in the opposite direction on the same track. Initial reports varied with potentially between 33 and 136 passengers injured, with up to 20 of them seriously although a member of the fire service later corrected this to 56. The actual figures were reported at 117 injuries (13 critical, 43 or 44 serious, less than 60 minor). On 22 April 2012, a 68-year-old woman died from her injuries. There were sixteen people still in hospital. On 23 May 2012, the last train victim in hospital was sent home.

The trains involved were an NS Class 2600 electric multiple unit, number 2658, and an NS VIRM double-deck electric multiple unit, number 8711. Neither of the two trains derailed. Passengers were reported to have been thrown against walls, seats, windows, and other passengers. Just before the crash, witnesses said one of the trains sounded a long hoot of its horn. Photographs show that the VIRM unit received moderate damage, with deformation at the rear of the first and front of the second carriage.

The accident occurred between Amsterdam Centraal and Amsterdam Sloterdijk stations, near Westerpark, suspending railway services between Amsterdam and The Hague as well as to Schiphol Airport on one of the busiest rail routes in the Netherlands. The local train was travelling between Amsterdam and whilst the Intercity train was travelling between and . By Sunday afternoon, traffic was partially restored with a full service expected by that evening. The stretch of line where the accident occurred is where trains do not travel at full speed. It is estimated that at the moment of the collision the intercity was travelling at and the local train at about .

Bus services were relied upon on to get people to their destinations during the suspension.

A reporter from ''de Volkskrant'' travelled on board the SLT train, immediately behind the cab. He reported the driver of that train stated she feared that she had just missed a red signal.

Emergency response

Emergency services were swiftly on the scene. Many people were rescued from the train wreckage either by using cranes or by being placed in a protective wrap, with some carried out on stretchers. A trauma helicopter was used to take some of the people to a nearby hospital. Many of the injured were treated on a bridge nearby. Those that had only minor injuries were taken to an Amsterdam hotel. People were reported to have suffered broken bones, bruising and neck injuries.

Investigations

Two separate investigations are being carried out into whether the train collision was by human error or by a technical fault on one of the trains. By 22 April, the damaged trains had been towed away by locomotives allowing technicians to inspect the track for damage. The director of Nederlandse Spoorwegen, Bert Meerstadt, stated it was still too early to guess the actual cause of the incident and it was necessary to await the conclusions of the investigation. The Dutch Safety Board (''Inspectie Leefomgeving en Transport'', ILT). The data recorders were recovered from both trains.

ILT accident research

The possibility of the driver having overrun a stop signal was taken into account during ILT's research into the cause(s) of the crash; however, Transport Minister Melanie Schultz van Haegen was quoted as saying that further research was required to see if initial findings would be confirmed. ''De Telegraaf'' reports that the driver may not face prosecution however as a report submitted by ProRail, the operator of the line, to the ILT, showed the signal in question was part of an older system and it is guessed that if it had been one of the more modern signals, fitted with upgraded safety equipment, the train would have stopped in time.

DSB research

The Dutch Safety Board First Generation, which only warns for signals at danger and enforces a low approach speed. An improvement, ATB-Vv (Verbeterde versie or Improved version) exists and could have stopped the local train before passing the signal. Although this system had been installed on the train and the signal in question was planned to support ATB-Vv, it had not been installed there yet. The DSB questioned the slow rate at which ATB-Vv is implemented in the Netherlands.

Despite both trains colliding at a low speed, the number and severity of the injuries was considerable. After the collision people were catapulted through the train and hit objects such as panels, seats and tables, causing severe injuries, and a single fatality. The DSB argued those objects have not been adequately designed for possible crashes. It recommended that train constructors should consider an improved crash-proof design in passenger carriages.

Aftermath

Prorail and NS paid compensation to victims. Dozens of passengers attempted to make fraudulent claims: one person tried to claim for a Stradivarius violin, while another claimed to have missed an important modelling competition because of the accident. The most frequently claimed loss was an iPad.
