The 2011 Alawwa rail accident, occurred on the evening of Saturday 17 September 2011, when a passenger train, Sri Lanka Railways S11, drove into an observation car at the back of a stationary Intercity Express train near the Alawwa railway station, approximately 60 km (37 mi) northeast of Colombo.

[1] The accident resulted in the death of five people, including a French national, a Thai Buddhist monk and the train driver, with over 30 injured.

[2] A three-member committee, comprising Nimal Dissanayake, retired Appeal Court judge, Sanath Panawella, Director Arthur C. Clarke Centre and Sarath Perera, retired Deputy Inspector General Police, undertook an inquiry into the accident in October.

The committee recommended several solutions including re-positioning of the signal system, maintaining a proper coloured light warning system and improving communication among drivers, control room staff and station masters.
