The order is 12515 then 12806 12842 till Duvvada where overtakes was given for 2 trains. 12806 should have come at 2039 then 12842 at 2046 but arrived at 2120 home division train sidelined for passing trains and this happens 4 out of 7 days what to tell about it. The main bottleneck is Rjy in SCR where all trains are taking 60-90 mins for 42km which should take 45-50mins for nonstop trains. Yesterday too happened the same. Even if it leaves at 2015-30 coro is not able to get line in KGP Shalimar due to locals at 1030. If coro took more time then Mysur hWH then there uis technical problem in rake which was attended in Vskp.
