Cherans story is diff, it used it have RSA with Navjeevan those days and PM at CBE....so train frm ADI used to come by 5.00pm and the same train used to go as cheran by night 10.15 apprx i guess....
But due to LHB conversion RSA was changed and from then, Cheran is gud...i travelled both in 3AC and 2AC in Cheran...its decent
