They will never alter TT of Udyan... It starts from SBC at 20:00 hrs and it departs from YNK not before 21:30 hrs. (It's just 27km from SBC to YNK but train takes 1 and half hrs). First Rajdhani overtakes it, then 22134 and many times 11013 crosses it. I have written suggestions to start this train from SBC at 21:00 hrs.... but nothing has happened till now.
