I travelled by 16571 exp from YPR on 3rd sept on it's maiden commercial run. The coaches were new and were manufactured in 2013 except 1st AC-cum-3A coach and one of the SLR.The response was not bad and the train had an occupancy of 40 to 50 percent. However contrary to SCR press release of the new train having 6 sleeper class, on it's maiden journey the train had only 5 sleeper coaches.The train was hauled by KJM alco loco.
