I was on 12773 SC-SHM A.C Express on it's inaugural run.Actually i was not all expecting to undertake the journey by a train since i booked my tickets 2 or a day prior to my journey date but luckily as i was checking for ticket availability i came across this train which was showing good vacancy so.....it just all came together,totally totally out of nowhere.I guess the timings have been tweaked since then because now it reaches RJY after noon but when i took the train it came close to 2100 hrs and was running pretty late as well.
