my experience has been end to end right from 1986 if i remember correctly, it had a 1930 dep from MAS and a 500 am arr i think and we used to take shan-e-punjab to Phagwara, eventually that link changed to deluxe due to time change, my father used to always complain " badi hilti hai raat ko..neend hi nahi aayi" to the speed in JHS section..lol..it was a delight to see it with twin diesel locos, BZA WAM4 and JHS/GZB WAP-1 before JHS WAP4 ("Ashok series..) became the regular link.
