I can't understand where these arguments come from. There is no train saving 40 min by bypassing VSKP. Even the fastest train YPR-HWH duronto just saves around 15 min by bypassing VSKP. You can check and compare the TT's of YPR-HWH duronto which bypasses VSKP and Coromandel which passes through VSKP to know the difference.
