Hi, Just had a look at COA station and kakinada's C&W yard in googlemap's satellite view (updated). To my surprise for the first time I have spotted 5 trains at a time in the COA and C&W:
1) Pitline 1 Gowtami
2) Pitline 2 Seshadri
3) Parking line adj to Pitline 2 - Might be COA-HYB APSRTC Strike Special
4) COA platform 1 - Circar
5) COA platform 2 - COA SC Tatkal special or COA- TPTY special.
May COA/CCT be busy at all times with regular trains like this in future. :P
