CRS reminds me of the famous dialogue"Aal is well" from the movie 3 idiots..Because in the movie all is well meant that u need to befool your heart sometimes to stop yourself from panicking ..The same goes with CRS..It doesn't mostly mean that if cRs test of a newly laid track or other stuffs like electrification etc is conducted then it will be totally fit for running of trains its only to befool our heart that a particular track is safe now..in shayari u can say that "dil ko behlane ko Galib ka ye khayal accha hai"
