cloning trains have not been started yet . and where and why should rlys provide seats to wl pax?? where will the extra seats come from?? rlys cant create seats in a train ! max 2-3 extra can be added ,, if all wl is to be accomodated then loco will give up seeing no of coaches ? already tracks are saturated and we have enough problems maintaining timings of existing trains in the trunk routes,, now if there is train cloning,controllers will commit suicide ,, didnt get the second part of ur question,, both sms ticket and printout is valid
