Sixteen bogies of an oil tanker train have caught fire near Mariani in Upper Assam.
The tanker train had left the Numaligarh refinery for Uttar Pradesh and was between Bhilgaon and Borpathar when it caught fire.
The fire is still raging. The track has been damaged so it will take some time for train services to resume.
All train movement to and from Upper Assam has been suspended as a result of the train fire.
