At the best of times, after Independence in 1947, photography on and about the Indian Railways has been a hide-and-seek game. You hide while you shoot, the Railway authorities seek, and if you don&rsquot get caught, then you publish and become famous &mdash as dozens of exhibitions and lakhs of online photographs will prove. The extensive grey area between amateur clicking and commercial work adds to the confusion. However, if you go about things unobtrusively, using new-age point-and-shoot cameras which often are not bigger than your palm, then the whole world of steel rails are your canvas, and very often you will achieve masterpieces.
