I don't think so, Vivek is going to skip VSKP. Whatever the TT is provided zone change over points , rest of the station they didn't mention. In the note change route is mentioned but not skipping of VSKP. By seeing TT between DVD-RU, 12727 is going to over take 15906, but 15906 has very less stops as compared with 12727. Off course we can expect Vivek may run late as it is coming from long distance.
