No, timing is perfect. It's not easy to get early morning slot at Delhi. If this train manages to get it, that'd be excellent.
People will have enough time to reach New Delhi Railway Station and Board Shatabdi Trains to continue their journey further.
There's already Bengaluru Rajdhani via Secunderabad arriving at your suggested time.
If this train gets 4 AM Slot that'd be...
more... perfect for people proceeding further.
Easier for people of Delhi to reach their homes change and rejoin offices as well.
There's a reason why Dakshin Express is highly popular among passengers of Hyderabad even after taking full 2 nights of journey.
And there's a reason why Chennai Rajdhani, Secunderabad Rajdhani, Chennai Duronto and Secunderabad Duronto aren't that sucessful. Nowadays 10 AM time isn't preferable for City like Delhi among the working class especially. People go for utility rather than comfort.
