On 9 November 2016, a tram operated by Tramlink, a light rail tram system serving Croydon and surrounding areas in South London, England, derailed and overturned on a sharp bend approaching a junction.[1][2] There were seven fatalities with 62 other people injured; nineteen of them sustained serious injuries. The tram was carrying 69 passengers.[3] It was the first tram incident in the United Kingdom in which passengers were killed since 1959.[1]

The tram was running from New Addington to Wimbledon via Croydon, and was on the approach to Sandilands tram stop soon after 6:00 a.m.[4] The second interim report into the accident indicated that although the speed limit approaching the junction was 20 km/h (12 mph), the tram had been travelling at an estimated speed of 73 kilometres per hour (45 mph).[5] Driver error was found to be the cause of the accident.[3]

Accident

Tram 2551, the tram involved in the incident, operating route 3 in 2010

The accident took place in the dark and during heavy rain at 06:07,[6] on a sharp left curve approach­ing the points where the route from New Addington (on which the tram was operating) converges with the line from Beckenham Junction and Elmers End.[4][7][8] The curve is located in a cutting, which comes almost immediately after the line emerges from a series of three tunnels on a 1-mile (1.6 km) straight section of track after leaving Lloyd Park tram stop. It has been described as a "sharp bend",[9] and has a 20 km/h (12 mph) speed restriction.

The tram entered the curve at a speed of approximately 73 kilometres per hour (45 mph)[5] and derailed, overturning on its right side and coming to a stand 25 metres (27 yd) beyond the point of derailment, damaging the side of the tram and ejecting several passengers through broken windows.[5] The tram involved was No. 2551, a Bombardier CR4000 constructed in 1998 by Bombardier Transportation, a two-section articulated unit with a maximum design speed of 80 km/h (50 mph).[5]

The emergency services confirmed that 51 people were injured, and initially stated that five had been killed.[9][10] The death toll later rose to seven.[11] The victims, six men and a woman, were between 19 and 63 years old.[12] Sixteen of the survivors were described as having serious or life-threatening injuries.[5][13] The final casualty figures were seven killed and 62 injured, 19 seriously. One person was uninjured.[3]

It was the deadliest tram accident in the United Kingdom since an accident at Dover in 1917 killed eleven and injured 60,[14][15] and the first in the United Kingdom in which passengers were killed since three people died in an accident in Glasgow in 1959.[1] It is also the deadliest accident on any rail network in the UK since the 2001 Great Heck rail crash.[15]
