HTE-YPR cannot be run daily since the same slot/path is being used by Tata-YPR (12289) and HTE-ERS (Weekly).
They can combine HTE-YPR & HTE-BNC since both originate at same place and thus make train triweekly.
Similarly this same slot was also used to run a SBP-YPR special as well. So in existing time slot HTE-YPR is difficult to be made daily.
