In train No. 5930 Chennai Egmore Express in the time table section the train is said to reach Andal from Siuri...then it goes to Durgapur and then to Asansol from there. Andal is inbetween Durgapur and Asansol...so how come the train first reaches Andal and not Durgapur...however..in return journey as 5929 it first reaches Asansol, then Andal, Durgapur and then Siuri which is quite normal.Is is a timetable error or there is some loop line issue for which 5930 has to come to Andal ..thn Durgapur...and thn turn bk towards Asansol...Can anybody help in this
