Loss toh nahi hoga I think..The amount of paasngers between NDLS-LKO h plus VNS bhi include krlo usme toh loss ka reason nhi aayega...N sumtimes timing utna nhi dkhte k 23:25 pe AC express h toh ise 23:00 pe depart krne ka kya mtlb h..Aise toh Sealdah n Howrah rajdhni bhi h 25 min k gap pe..Amount of paasngers is the key here I think..
But still is timing se Ise AC express n LKO mail dono Ko overtake krna pdega..
