Yes i agree this train has a serious punctuality issue never arrives destination on time....even ER does not give priority to this train from ASN to SDAH stretch.....gets delayed in this section also....ER has too much of mail/sf/premium trains but most of the trains have a very slow and worst TT and punctuality except the rajdhanis most are slow TT. I have earlier wriitten to RB to stop some of these slow TT loss making trains in the busy hwh to dli and even asn -pnbe route this will lessen the congestion in this route...some trains that block the route and create congestion i see is
Sdah-varanasi upper india
Sdah...
more... -dli exp
Kol-pnbe exp(earlier used to run till dli merging lalquila &janta exp now short terminated till pnbe)
Hwh -asr exp - needs speed up with few halt removal
Doon exp-needs speed up
Bagh exp- needs speed up
Udyan abha toofan exp
Koaa-jat exp needs speed up removong few halts
And many more to name. These trains has very slow TT creating congestion . These trains either needs speed up to remove congestion and railway can stop few of them or short terminated them....because of few such trains some hood trains like yuva exp,duronto exp both sdah and hwh, himgiri, etc gets late everyday.
