Quota is too less for TIG for a train that has 22 coaches. Same issue from Korba Raipur is placed under RLWL and is in WL but available from Bilaspur. Seen your other posts for Samatha and LTT express which should be General quota upto Raipur. Though it's in ECOR bad allocation of quota. Put your request in Visakhapatnam Jn. Facebook page. That page has some direct links with DRM office. Try once.
