Crawler term used coz of stops not Duration
BKP-DDU-BKP: Faster than Himgiri, Vibhuti, Magadh etc. * PNBE-DDU-PNBE: 9 stops faster than Ziyarat, NE, Seemachal, Ananya etc * DDU/ARJ-NDLS: Faster than Mau-ANVT SF, Suhaildev, Neelachal, HWH BKN SF (All LHB)!!
Crawler doesn't justify this train which usually run @ MPS throughout its span, is high on priority in PNBE-DDU & OT Himgiri unusually in BSB-SLN Section!! Its schedule drafted to adjust PPTA-CSMT SF, INDB Exp, BSB/SLN-ADI, Harihar which cant be done for Crawler!!
