It looks like they just building new waiting rooms other buildings I think long back it is said that station will be redeveloped like smvt, Rani kamlapati stations like new flooring, entrance, concourse similar to airport tirupati too was selected in same scheme but now it looks like normal redevelopment considering revenue it don't need to be like a airport like others but something similar to that is expected
Tirupati,RJY,NLR,WL,BZA station need more development considering they are important main Line stations
