Once Duvvada in SCR only after that it merged into ECOR....Making duvvada big station wont solve VSKP city people problem...
Duvvada will be use full for Gajuwaka, Vizag steel plant, NTPC townships, VSEZ, Anakapalli, May be parawada too...
But vizag city and Bheemili, Vijayanagram, Srkakulam this is almost 60-70 lakh people use VSKP station only....So i dont think Duvvada is helpful....
If...
more... they want to skip all trains Simhachalam North need to be developed for trains from North...and duvvada for south...
