bro it is not a matter of which train running via which zone.late train in ald-cnb-ndls section due to poor section control by ncr zone guys.why ncr train like prayagraj,ald duronto,shramshakti not getting too much late is this section.if you run sampoornkranti,ald duronto,prayagraj depart in 10 min differnce time from ald.the ncr guy stop sk and get pass to ald duronto,prayagraj,shramshakti etc.
