Eight people were injured after four coaches of a Delhi-Darbhanga train caught fire on Wednesday.
The fire erupted in the S1 (sleeper) coach of the 02570 Delhi-Darbhanga Clone Special near Etawah in Uttar Pradesh. The train was passing through the Sarai Bhopat station when smoke was noticed.
A video from the spot showed a massive blaze engulfing one of the coaches as passengers and officials stood around it. All trains to Bihar are packed because of the Chhath festival.
