I saw these timings in a news paper few days back....Vaigai and pandian reduced by one hour....Now the vaigai is taking approx 7.30 hrs travel time....if it reduced to one hour then approx 6.30 to 6.45 hrs....Like wise pandian takes 8.50 hrs now after speeding up it will reach in 7.50 hrs....Like this they had mentioned in news paper
