what passengers did...chart prepared. ..filed tdr but travelled. ..
if tte were efficient, tdr was rejected
if tte dint check, money got refunded...
so...
more... later irctc took stern steps...
u cant travel, file tdr asap...
with prs tickets its different as derz a hard copy of d tkt...wd e tkts its jus a sms or a printout...
