The Darjeeling mail is one of the oldest and VVIP train in India. Well,as a regular passenger of the DM i think the train should be provided with LHB rakes instead of ICF coaches. As it has the highest number of 1 AC=1, 2 AC=2, 3AC=7, SL and GN rakes, i think the tarin should be provided with high comfortable LHB rakes.
