I either take Dnr-Sbg Intercity or Pnbe-Dhn Intercity. Have booked in JanShatabdi too, but missed it everytime. Last month I booked in DNR-Tata [but left it to board Dnr-Sbg at the last moment and that decision is history :( :( ]
Mostly it's a break Journey for me- From PNBE to KIUL and then From there by Passenger trains.
For my next Journey, I opted for 12306 over 12310/12394 just to make sure that I can catch 13236 easily.
