My last Journey(Shuttle EMU) Was in April'2002.(TUNI-VSKP :; I remember that journey very well -- a day after my first visit to HYB). The Service Might have been stopped in 2003.
The First Passenger Train to VSKP was 1VK/2VK
Followed by Waltair Bezawada Passenger,MTM/NS Passenger.
Last one Should be the Current Running RJY VSKP RJY Pass(1997/98 or so -- Approx)
