Railway tracks damaged by the derailment of the Kalinga Utkal Express in Uttar Pradesh will be repaired by Sunday night and traffic restored, officials said.

The busy rail route passing through Muzaffarnagar district has been badly hit since the Saturday evening disaster. Several trains have been diverted after 14 coaches of the train derailed near Khatauli.

An official said trains were being diverted through Tapri junction.

The diverted trains include New Delhi-Dehradun Shatabdi Express, Dehradun-Mumbai Central, Haridwar-Ahmedabad Express, Jalandhar-Mumbai Express, Amritsar-Bilaspur Express, Mumbai-Jalandhar Express and Bilaspur-Amritsar Express.

The accident was so severe that some of the derailed coaches mounted on others.
