Narsaraopet-Vinukonda doubling.It is my observation during journey in prasanthi exp at night time. The land levelling started from narsaraopet outer and completed almost till vinukonda. Only a little portion is not levelled in between vellalacheruvu and savalyapuram. Major bridges b/w savalyapuram and VNk, vellalacheruvu-savalyapuram is completed. A new station building is constructed at santamaguliru.land levelling works completed almost till vinukonda outer except a very small strip . It is also observed that works are also going in night time. If they really take-up work, satuluru-vinukonda can be completed this year. Huge ballast procured at savalyapuram station. Only two major bridges pending and also pillars are laid for bridge. Only slab works are pending for both the bridges
