Instead of disturbing existing trains, SR should run new MAS MAQ SF Via KJM HAS.
From Chennai side, we do not have any train after Lalbagh at 1530 towards Bangalore. So, new MAQ SF can start by 1630 and cross KJM by 2230 and reach MAQ by 0800.
From Mangalore side, no trains are there in the afternoon towards Bangalore. So, it can start by 1400 and reach KJM by 2300 and reach Chennai by early morning. Alternately, it can start late in the night by 2230 and reach KJM...
more... by morning 0700 and reach MAS by 1300.
