No, only stations of Mumbai and Pune Junction in Maharashtra were NSG 1.
Someone shared the entire list in 2018, I just saw it yesterday. Someone had rated it, but I'm not able to find it.
Total 21 stations were NSG 1, 14 based on revenue criteria and 7 based on footfall criteria or something similar to same.
I don't remember exactly, mostly there...
more... were stations of Metropolitan Cities like Tambaram, Chennai Central, Chennai Egmore, Kalyan, Mumbai CST, LTT, Dadar and terminals of other Metropolitan Cities. Patna Junction, Surat Junction, Pune Junction were on the list too.
Someone should share if they remember the original post
