Most of the current trunk routes are in existence since British India.
So, from wherever they passed the lines, continues to be major route even today (be that small town or village).
IR doesn't bothered that much in including big cities on trunk routes by realigning them.
please wait...Translate to EnglishAll the main roads we use today were made during British India. So, wherever they built the roads, they are still major roads today, whether it's a small town or village. Indian Railways doesn't really care about adding big cities to these main roads by changing their direction.
please wait...Translate to HindiBhaari India ke dauraan sabhi major rail routes bane aur aaj bhi vohi ruk ruk ke chalte hai bade shahar ya chote gaanv mein. IR ko fark nahi padta ki major routes se big cities ko baandhne ke liye unhe modify karna padega ya nahi.
