Slightly off topic, but long ago I read in newspapers that in british era, there was a line from Ambikapur(Chattisgarh) to Barwadih(Jharkhand). Baad mein band ho gai ye line kisi kaaran se. Abhi agar ye line fir se banai jaati hai, to ek aur naya east-west route milega. Kota-Bina-Katni-Anuppur-Ambikapur-Barwadih-Dhanbad can be very useful.....
