Now this is routine Job. Poor efficiency of Danapur control derail the train timing , especially for down train. Trains used to take two hour to three hour from ARA JN to Patna Jn, situation is worst between Danapur and Patna jn ( Now a days five major trains terminate at Danapur/Patliputra , and Four Major trains at RJPB then why train always delayed between Danapur and Patna and vice versa.
