Oh So Sorry.I think most part of the UP Map has Single Lines.But I had seen quite a few videos of Amritsar Mail & Himgiri Exp b/w Varanasi & Lucknow,where it was Double track.May be I think close to big junctions,they've made Double Line.Elsewhere Single ;(.For Eg,whole SBC-BZA(via SCR)is Single,only section b/w Guntakal-Gooty,Guntur-Vijayawada is Double,because Guntakal & Guntur are Divisional HQ.)
