Old Ticket - By 1993, the 11 Sleeper - 3 Tier was replaced by Sleeper Class. Cochin Harbour Terminus - madras Central ticket in Sleeper class by 6042 Express on 14-10-1994. S4 Coach Berth No. 54. I traveled with all the above tickets during my college days in Chennai. I found a large bag of old tickets sometime ago and was lucky enough to get hold of these!
