It's a blessing of a train jinko Kolkata se mines jaana hota h, places like kiriburu, meghatuburu barbil se bohot easily accesible hain aur kolkata mein there are a lot of Headquarters like SAIL RMD, etc.. jinko mines se aana hota h on a weekly basis it's somewhat their only option..
Haan TATA aur KGP se there are better options
