Brother, as u said "timings should be arranged to cause less disturbance to others"... pls don't take me wrong, but what I feel is that as of now we just need to wait for the speed limits to be increased from.... say.... MAS till JTJ... and who knows, our VB can reach the destinations faster than before.... this is not only for VB, but also for Shatabdi, Brindavan, and all others trains covering this section.... be it the MAS CBE Shatabdi, or Kovai SF Express... so I think, maybe within few months... they would do the speed trial test any minute and once that's done, almost all trains using that section, those trains' avg speed might increase leading to reaching the destinations faster and earlier....
