around 4 yrs back meeting was held at UBL to extend CSTM -SUR mini siddeshwara SF up to gadag at that time itself it was decided to cancel this train ,reason becz of its matching TT with this train..so i dont think they ll reintroduce it again ..also they r making GDG-CSTM exp daily one more reason they ll add .. they should merge these coaches with CSTM -GDG exp and adding some more SL coaches ..extend ie up to HPT or UBL with some TT change in return direction ..
