Rajeev, with a number like 22633 (with 126xx or 226xx being indicative of a southern zone, either SR or SWR), which zone should this train belong to, according to you?? NR is running 3 of the four southern Rajdhanis namely, the ones to Chennai, Hyderabad and Trivandrum. SWR has succeeded in getting the two Rajdhanis for itself because the 12213 Duronto belongs to NR.
