Antiguo tren de carbón cruzando un desierto dorado al atardecer

A realistic old coal train moving through a vast golden desert at sunset. Smoke rises from the engine. Inside the train, an elderly grandmother wearing a simple saree sits near the window, peacefully eating a ripe, juicy mango. She smiles, finishes the mango, and casually throws the seed out of the moving train window. The mango seed falls onto the dry, cracked desert sand. Cinematic, warm sunset lighting, ultra-realistic, 4K.
