Correct..
If you see HWH-PURI Weekly and HWH-RNC Tri-weekly routesTT are matching very much with Shatabdi exp TT only few hrs ( say 30 to 40 mins gap) difference between them... .. Either any 1 train will get passenger and another will be empty if bidded by private players or Shatabdi exp in those days will be Cancelled and private trains will run..... both cannot run... but that will depend if these trains are bidded by any private companies.
