The Delhi-bound up line at the accident site near Raghunathpur railway station in Bihar's Buxar district has been restored and work is underway to repair the down line, the East Central Railway said on October 13.
The up line is ready for limited movement of trains but normal movement on this route will be allowed only after restoration of the down line.
Four people were killed and several people were injured after 23 coaches of North East Express, on the way to Assam from Delhi, derailed near Raghunathpur railway station around 9.53 pm on Wednesday.
