Not a problem with the time-table I guess. This is running in the 5 hr gap between 11041 and 12163. Other than Jayanti Janata running 20 min behind this at RC, there are no other trains to overtake this. GTL-RU is also doubled so no problem with crossings. Might be some operational reason or freight traffic being given priority. But there is a huge slack before between Koduru and RU ( 2hrs for 40km), so the delay will most likely be covered by the time it reaches MAS.
