I'm just telling some trains like FD RMM and BBS RMM are not at all needed for MDU and you are wanting those trains to be dumped there. And ur talk is like comparing MDU and CL , which is an even more utter disgrace to MDU. The need is for Kashi , and you are talking of MDU AY need from nowhere. TNSK can have diversion via ML. Delhi has the lesser demand among metros. And so u have TNSK since ML is the only place that can fill Long-distance train according 2 u.
