Little tough till Bangalore. Train reaches at TVC 14:20. After that it will have to go to yard for maintenance. Which will take 7 to 8 hours. So finally rake will be free only from Monday Early morning. So if it need to go to SBC, then it will have to run as day intercity, in order to reach it back by tuesday night, so that it can start its journey back to NZM on wed 1AM.
This will be kind of tight run, as long distance trains are prone to get delayed, due to random issue. One delay will affect entire pattern of trains which might need to cancellations of few services.
