The Seemanchal Express derailment occurred on 3 February 2019 near Sahdei Buzurg in Vaishali district of Bihar, India.[1] Six people were killed and more than 30 were injured.[2][3]
Investigations suggested that the derailment happened because of a fracture in the rail line. Because of the sudden impact on the broken rail, the locomotive and a few cars decoupled and overturned.[4] A passenger who survived the crash described hearing a loud bang and falling to the floor of the train.[5]
