I have got an SMS immediately when chart has been prepared for original train (Poorva Exp) The msg was like " PNR 25590***** provided accommodation in new Train No 12260 from NDLS to SDAH under ATAS scheme. Please check PNR Enquiry for coach, seat and boarding info" Hope this information will help other too. Thanks.
One can opt out as well from Vikalp if he is not interested for get ATAS, but it should happen before berth allotment. And if you don't want to travel on the new alloted berth/train then you have to pay cancellation changes as per the new fare for which berth has been allotted.
