sir dont beilive indiarailinfo....here if you ask any admin,what is the diff b/w Naranarayan Setu & Saraighat Dolong,No one can answer,because they dont know the diff b/w Goalpara sector & Rangiya Sector...today one of our admin was travelling in Saraighat Exp..our website trip diary showing train crossed patiladaha,whereas train @ that pt of time @ Dudhnoi...Saraighat is a permanent train in Goalpara sector...if that mistake is possible by our admins,then KOAA DBRG is a weekly & admins will never correct the mistake
