ALJN-LKO via CH-SPN is 398 kms while via CNB is 382 kms just a difference of 16 kms......
ALJN-GD-GKP via CH-SPN-SCC is 635 Kms while via CNB 658 Kms ?? even less.....Thats why I think they are planning.
And loco reversal at Aligarh will require less time as to detach E Loco from front and attach WDP 4/ 4D at the back.
I sincerely...
more... believe that sooner or later they will have to explore this option, somehow some one needs to show the above to the concerned authorities.
