Rahul, u know the number of trains connecting delhi and stations from Nagpur, and u know the number of trains connecting Delhi from all the southern states, Obviously the trains are more from Nagpur towards delhi, after itarsi,Bhopal and Jhansi number of trains even increase, There is demand, but there are trains.
If you have ever visited SC, then you can see the number of passengers getting down at SC, I myself have travelled in this train thrice, "the demand and availability are never met".
Finally, this is like a combined Raj...
more... for both AP and Karnataka because the SC Raj is a weekly train and people from SC depend on this and duronto for fast travel.
My bottom line is" Iam not commenting on other enroute stations, anyway as i have mentioned earlier, the statistics show the connectivity, Here Iam talking about Hyderabad only"
