Railways are bringing up BNC as starting point for these odd trains. Frequency should be hourly round the clock.
But how people from west/ south Bangalore will reach BNC? No direct buses from Kengeri/ Vijaynagara/ Rajajinagar/ Magadi road/ Jayanagar/ JP Nagar/ Kanakapura road/ Banneerghatta road/ Koramangala/ Sarjapur road etc. Dedicated BMTC bus services can help. Else this effort will be a flop.
