In many stns in UP one can see grasses have grown over tracks or tracks have been soiled down but that is not the case with NFR.. Track maintenance is of utmost priority & even remote stns in bg3 like Damdim or Bagraquote where rarely any xings take place, evn the looplines are always fit & encroachment free from any kind of flora or fauna.. This practice has to be mandatory all over IR.
