GZB WAP Locos serve trains between ASR and SRE/MB/LKO if there is any loco change in NR. The same happened for 12358 Durgiana Express when it wasn't electric hauled on an end-to-end basis. I feel that ER should place an order to the Railways Ministry's ICF or RCF for LHB Rakes. The journey is tiring from Howrah to Punjab and back!!!
