I couldn't from my relatives, so how could I suggest you? My experience was with 12817. For one full month in 2017 regularly it ran bang on time or hardly an hour delay, and I suggested the same to my relatives to delhi, and unfortunately that day it ran as it used to run previously and reached delhi with delay of 8 hrs around 10 pm. After that I got good metaphors from my father ЁЯШБЁЯШБ. After that incident I dont suggest any train except rajdhani to my relatives for delhi. Take it or book in any train of your choice but spare me.
