Vaigai வந்துருச்சு, ஆசையில் ஓடி வந்தேன்

Can someone tell me what is the seating layout for this train? As per IRCTC charts it has 3+2 layout in some coaches and 3+3 for some coaches. Now in the coaches where there is 3+2 layout the middle seat is showing even as Windows seat. I got 41 in D6 as per IRCTC chart it is between 42 and 50, then how come its windows seat? Can someone clarify this please?
