I am resident on 2nd floor and two balconies of my flat face the train track. Few things I can say - 1. While trains do pass by, the track is around 3-4 hundred meters away and not immediately next to the boundary. 2. The frequency of trains is very less. I have not noticed more than 2-3 trains in a day (max). 3. Trains usually honk near K R Puram station and not necessarily when they pass the apartment. I have barely noticed any horn sounds from trains. Hope that helps, VishwastamI am resident on 2nd floor and two balconies of my flat face the train track. Few things I can say - 1.
