Gudur - chennai distance is almost same as kazipet - secunderabad. Chennai central is deadend station which needs almost every train to occupy 25 min. Ofcourse it has seperate 4 more platforms for local trains but eventhen chennai central trains are getting delayed by 10-20 min only. Chennai also has lot number of incoming and outgoing trains during morning hours. Why does it is getting delayed only for secunderabad station. It is time to think very deeply on this. Dear officials of SCR it is the case with tirupathi station also. Trains coming to secunderabad and tirupathi forgot to reach ontime.
