bro people use ns smvt when going to bengaluru in return they may use sheshadri or kondaveedu if both are booked then they will book for this train sheshadri reaches gdv to ndd in early hrs even kondaveedu only covers gdv but can't cater kaikaluru akiveedu bhimavaram so these area people will definitely use this even if they don't want to catch at smvt means they will go to bangarpet and travel in same train bro
