Raipur tak rajdhani isliye nahin chalti hai kyunki chahe ngp route ya katni, dono taraf se ya durg ya bsp, dono mein se ek important station chutega.
Eg patna. Bihar rajdhani patna ke bajaye Rajendra Nagar tak jaati hai. Vahin kisi aur zone se aane wali gaadi patna ke bajaye danapur mein khatam hoti hai.
