Hhm actually correcting on IRI will be not the complete solution as it is not going to use for ppl who are not using Internet to check train timings they depend hardly on station announcement and display at stations. so need to rectify such silly confusions/mistakes from root and that is Indian railways try to make reach your this problem to MOR and RM and concerned Train DRM and General Manager on twitter and any how moderator sir on IRI may take steps to do any solutions for such problems. The train I told Now it's displaying correctly and it also converted to DEMU now so I didn't complain abt it but Railways themselves corrected it..
