I&rsquom walking toward the steam loco shed at Rewari Junction, not far from Delhi, and it&rsquos the mother lode for people like me, who are loco about steam. It&rsquos not hugely well-known, but steam engine fanatics, primarily from the UK, Japan and Europe, have been visiting the Rewari Steam Centre in a steady trickle. There may be other places to see beautifully preserved steam locomotives, and there are occasional opportunities to see them run, usually for special or commemorative runs. But Rewari is one of the few places in the world where you can regularly see a workingsteam engine in all its clanking, smoke-pumping glory.
