One of worst Hybrid LHB rake of NR/IR. 105 mps Shalimar rakes used from long time in Delhi-Jammu route.
This indirectly proves eperiment of IR i.e Hybrid LHBs are not a success in IR for following reasons
1) some rakes 105-110 mps while some are 120 mps
2) 120 mps rakes also getting replaced by pure LHB rake. i.e MAS-NZM Duronto
3)...
more... As per CR, WAP4 is not suited for Hybrid LHB, hence all Hybrid via CR be it 110 mps SKD, NGP Duronto or 120 mps SC Duronto are given WAP-7.
Hyrbid LHB production getting stopped itself is big proof for its failure. Again experiment is done pure sleeper LHBs are produced and are made to run at 130 kmph! Time will decide how successful are they!
