she may complain temporrily in NJP,but I suggest you to complain in NR...normally all the trains which when passes through respective division has their home staff....but Rajdhani & Duronto are one of the very few trains for which staff is decided based on which zone the trains belongs to...So TTE is basically NR staff..though if she complains to Complaint Box available to Guard,then Guard will be from NFR/APDJ Division ex NJP-GHY
