Artist Kishore Pratim Biswas was six years old when he first spotted a steam locomotive engine in Kolkata, his birth city. He was mesmerised by it. The steam emerging from the engine, the motormen and other railway staff members who worked hard to keep the train operational — all this imagery captured his imagination. Biswas took to sketching and painting with watercolours to recapture that childhood memory whenever the opportunity arose. Since then, the 52-year-old has created several artworks of these old engines, which have been displayed at various exhibitions in Delhi, Mumbai and Kolkata.
