Guwahati: Three bogies of the 5960 down Dibrugarh-Guwahati-Howrah Express jumped off the tracks following a bomb blast in Central Assam's Karbi Anglong district in the early hours on January 20, according to NF Railway sources.

However, there was no report of any injury so far as the bogies that derailed included an almost empty general compartment, a parcel van and a brake van, they said.

Tracks have been damaged on the single line broad gauge section due to the explosion and the subsequent derailment and the Railway personnel were working on rescheduling trains passing through the section until the tracks were repaired.

The derailment of the Howrah-bound train occurred under Diphu-Lumding section of NF railway between Diphu and Nailalung stations just after it had left Diphu around 1.30 am (IST) for Guwahati.

Police said the bomb was planted by suspected militants on the tracks, which exploded as the train passed over the rails.

Stating that the identity of the insurgent outfit responsible for the explosion was not immediately ascertained, police said the militant United People's Democratic Solidarity (UPDS) whose factions were opposed to the ongoing talks between the Centre and the Nagas were active in the area.

Altogether 60 buses have been pressed into service for trans-shipment of the passengers of the train as well as the Dibrugarh-Guwahati-Delhi Rajdhani and the corresponding Howrah-Guwahati-Dibrugarh Kamrup Express which were scheduled to pass the area on January 20 morning.

A relief van, a medical van with doctors and para medical staff and senior NF railway officials had immediately rushed to the site as the guard informed the railway authorities of Kamrup's derailment.
