Nomenclature tags such as King and Queen are 'fondly' used within RF community only. Indian Railways doesn't consider trains with such suffixes.
IRI is navigated by non RF community people too hence abiding to train's official name is preferred as it's been as such since inception. We have a section for other name as 'Kolkata Rajdhani' which is used popularly by the civilians.
please wait...Translate to HindiNomenclature tags jaise King aur Queen 'pyaar se' sirf RF community mein hi istemal hote hain. Indian Railways aise suffixes ke saath trains ko consider nahi karta. IRI non RF community ke logon dwara bhi navigate kiya jata hai isliye train ka official naam follow karna jyada pasand kiya jata hai kyonki yeh aise se shuru se hi hai. Hamare paas ek section hai dusre naam ke liye jise 'Kolkata Rajdhani' ke roop mein civilians dwara popularly istemal kiya jata hai.
