now that this train has a 30 min stoppage at HW railways should attach extra coaches at HW to make this fast but weekly a 24 coach train for it to serve any meaningful purpose. presently DDN can take only 13 coach rakes and it is a criminal waste of precious energy and prime slot to run this train with 13 coaches only for 3500 km. railways should, in fact, attach extra coaches at HW to all trains using 6 AM dep slot from DDN, i.e., DDN-INDB, DDN-UJN, DDN-OKHA and also DDN-MDU trains to increase their capacities.
