This month NDLS SF Express from HWH got LHB rake..Don't know about SDAH-SDVK Express !! A rumour is always here that Kalka Mail, Darjeeling Mail will get LHB rakes soon..I think SDAH-SDVK Premium Express from has long time to introduce ! No news of the train right now..And 22313/22314 is not AC Express, its a normal train with premium tag.. :P
