Exactly what I said, "Bahut fast hai, 12424 Rajdhani bhi 65 hi nikal paati hai." Now you are saying max average should be 70, I assume that's only possible in some group A or group B route. North East ki trains (upper Assam) max 55-60 hi nikal payegi when it travels almost 500km of it's journey on single line with 100 kpmh mps.
