Crew change @ KNW/BD isnt gonna happen (even if feasible) as BSL exist perfectly for CC (acts as center for both NGP & BPL)!! Further, train need to get 90 kmph avg in CSMT-KNW to cover in 6-7 hrs for CC (impossible without 150/160 MPS) & 75 in CSMT-BD (130 MPS)!!
KNW/BD isnt CC point, even when CC @ IGP creates route possibility!!
LTT-BSL-JHS-NDLS & LTT-BSL-NGP will remain CC even with IGP stop or Push-Pull!!
